+XII ANNOTATING
+--------------
+
+Tout d'abord, voici les notes documentaires qui ont été réalisées sur
+la problématique d'annotation d'image. On trouvera un fichier
+class.txt qui a pour but de poser quelques réflexions sur les types de
+classes de document. Les informations ne sont pas abouties mais
+permettent de défricher un peu le terrain. Le document
+syntheseMillet2008 est un compte-rendu de lecture des parties
+relatives à nos travaux dans la thèse de Millet. Pour bien comprendre
+mon travail, il est impératif de lire les travaux de Millet, ou
+simplement ce compte-rendu. Le dernier document est moins intéressant,
+il s'agit d'une note de travail sur les indicateurs de Millet bruts de
+fonderie (testMillet2008). Cette note n'est ni achevée, ni
+aboutie. Elle conclue sur le fait que les indicateurs et les seuils
+donnés par Millet dans sa thèse sont complètement à revoir pour nos
+besoins. Notemment, des tests sur la détection des images par rapport
+aux cliparts nous ont convaincu que certaines images AFP contiennent
+des de grandes zones homogènes qui induisent des erreurs dans les
+prédicteurs de Millet. Néanmoins, les cas particuliers qui
+contredisent les aspects opérationnnels de Millet n'enlèvent pas sa
+réflexion: Les images noir/blanc (ou monochromes) ont une très faible
+saturation, et/ou une forte concentration de la teinte. Les cliparts
+ont une forte concentration de niveaux de gris autour d'un pic.
+
+* doc/annotating: La documentation relative à l'annotation.
+
+
+Après la lecture des descripteurs de Millet, un des premiers réflexe a
+été d'en implémenter plusieurs pour voir ce qu'ils pouvaient ressortir
+sur les images que nous avions. Le descripteur BIC sépare une image en
+deux ensembles de pixels, les points intérieurs et les points
+extérieurs. Les points intérieurs ont la propriété d'être de même
+couleur que leur 4-voisins. Attention, la couleur est évaluée dans un
+espace RGB à 3 bits.
+
+* demo/annotating/bic: Histogrammes des points intérieurs et extérieurs.
+
+
+Le descripteur LEP, lui, propose de seuiller par sobel l'image et de
+faire l'histogramme des configurations du voisinage des points
+seuillés. Pour ce faire, on utilise une convolution un peu spéciale
+qui va attribué un unique id en fonction du voisinage.
+
+* demo/annotating/lep: Histogramme des configurations des voisinages des pixels.
+
+
+Un autre descripteur simple est le nombre de couleur dans une
+image. Pour cela, il est possible de construire l'histogramme des
+couleurs et de compter les cellules pleines. On peut éventuellement
+appliquer une quantification sur l'espace des couleurs. La
+compilation laisse place à d'étranges warnings sur une comparaison
+entre entiers signés et non signés, mais je n'ai pas la main dans mon
+code (ou je ne sais pas comment faire) pour enlever ces warnings. Ils
+sont récents, je n'avais pas souvenir de les avoir eu.
+
+* demo/annotating/nb_color: Compte le nombre de couleurs dans une image.
+* exp/annotating/nb_color: Adaptation pour fonctionner sur une base d'image.
+
+
+L'histogramme RGB-64 est un descripteur simple qui quantifie les
+couleurs sur 2 bits et réalise l'histogramme dans cet espace. C'est
+bien sûr une classification gros grain, mais ajouté au reste ... La
+version RGB-64-9 ajoute une phase de division de l'image en 9 sous
+images. De cette manière, l'histogramme RGB-64 est construit sur les 9
+sous images. Pour former le descripteur final, on fusionne les neufs
+histogrammes.
+
+* demo/annotating/rgb_64: Histogramme couleur dans l'espace RGB-64 (2 bits/axe).
+* demo/annotating/rgb_64_9: Histogramme RGB-64 sur les 9 sous images.
+
+
+Le descripteur de projection relaté par Millet est particulier. En
+premier lieu l'image est sous échantillonnée pour réduire sa dimension
+à 100 x 100 de manière à borner la taille des vecteurs obtenus au
+final. Puis l'image est seuillée par sobel (threshold = 100). L'image
+est d'abord divisée horizontalement en deux. Puis on établit la
+projecton perpendiculairement à la séparation de manière à obtenir
+deux vecteurs de 100 valeurs chacunes. On recommence l'opération en
+divisant maintenant l'image verticalement. L'union des 4 vecteurs
+forme le descripteur de projection. L'information condensée dans ces
+vecteurs est simplement la répartition des contours de manière
+horizontale ou verticale.
+
+* demo/annotating/project: Répartition des contours horizontaux et verticaux.
+
+
+La reconnaissance des cliparts s'appuie sur une analyse d'histogramme
+qui est fournie dans le code suivant. L'idée est de dire qu'une image
+de type clipart va être reconnaissable surtout à l'aide de ces
+contours. La couleur existe mais est très grossière. Le faitde
+dessiner à la main implique de simplifier énormément, de caricaturer,
+le remplissage. Du coup, une analyse en niveau de gris de
+l'histogramme révèle très peu de nuances. Il peut cependant en avoir
+un peu. Néanmoins, il existe des logiciels pour aider à la fabrication
+des cliparts qui proposent l'usage de dégradé, ce qui nuit à cette
+méthode de reconnaissance. Millet analyze l'histogramme normalisé
+(histogramme divisé par son pic) et regarde si son energie ne serait
+pas concentrée autour du pic (5 pixels de chaque côté
+maximum). Parfois cette méthode ne fonctionne pas correctement sur des
+photographies qui ont un cadre uniforme. La méthode trouve un pic (le
+cadre) et vérifie alors qu'une proportion non négligeable des pixels
+sont bien autour de ce pic (tout dépend de l'épaisseur du cadre). Pour
+palier à cet inconvénient, Millet propose d'utiliser ce test, non plus
+sur l'image entière, mais sur chacune des 16 sous images après un
+découpage géométrique régulier. De facto, la contribution du cadre
+diminue suffisemment pour repasser en dessous du seuil de
+reconnaissance.

+* exp/annotating/stddev_color_16: Adaptation pour le travail sur base.
+* demo/annotating/stddev_color_16: Descripteur pour cliparts avec 16 imagettes.
+* exp/annotating/stddev_color: Adaptation pour le travail sur une base d'image.
+
+
+A partir de maintenant, tous les morceaux de codes réalisés préparent
+directement ou indirectement le résultat de la classification des
+bases (exp/annotating/bench).
+
+Plus de temps pour faire le code use correspondant aux fichiers
+librairies. Tout le code pour le faire est dans hsv. Rien de
+compliqué, mais allons à l'essentiel.
+
+Le but du code HSV est d'effectuer les tests de Millet ou des
+améliorations sur ces tests. Le premier test proposé par Millet est
+l'achromaticité. Il s'agit de regarder s'il existe une faible
+variation entre les trois canaux (R/G/B) pour un grand nombre de
+pixels. Si c'est le cas, c'est que l'image est presque en niveau de
+gris et peut être remplacée facilement par une image grisée sans trop
+de distorsions au niveau de la couleur. Nous avons essayer de
+généraliser un peu le test de manière à produire, non pas seulement
+une réponse sur l'achromaticité de l'image, mais aussi avoir une vue
+d'ensemble (sous forme d'image) des variations entre les cannaux pour
+chaque pixel. Il n'est pas utile d'analyser les différences sur chacun
+des canaux, prendre la différence absolue entre le canal min et le
+canal max suffit pour définir le test d'achromaticité.
+
+Les autres tests de Millet sont la faible saturation et la dominance
+de la teinte. Pour savoir si la saturation est faible, il faut
+utiliser un histogramme du canal dédié à la saturation. Si 95% des
+pixels sont en dessous de 100, alors l'image est faiblement saturée,
+elle est en noir et blanc. De la même manière, on regarde la dominance
+de la teinte. Pour ce faire, il faut voir si l'histogramme de la
+teinte ne possède pas un pic avec une très faible variance (tout
+rapproché autour du pic). Si c'est le cas, la dominance de la teinte
+est avérée et l'on peut calculé la couleur dominante. L'image est en
+niveau de gris, mais colorisé autour d'une couleur (par cepia, vert
+...).
+
+Ce programme est très très sujet à changements, il m'a servit de test
+et je ne peux pas juré qu'il est complètement sain au niveau du
+traitement. D'autres versions sont potentiellement plus

+Dans le répertoire exp/annotating/hue, on trouve 3 fichiers textes qui
+rassemblent des classes d'images. Tout d'abord les images ICDAR
+n'ayant que du texte et des traces de couleurs (lettrine de couleur,
+trait, petit bandeau), un fichier où il n'y a que du texte noir &
+blanc et un fichier contenant les images couleurs (avec photographies
+ou dessins). Cette classification a été effectuée de manière manuelle.
+Le code hue test la proportion de pixels étant autour du pic de
+teinte. Il s'agit de savoir si la dominance d'une teinte est
+avérée. Le code renvoit la proportion de pixels agglomérés autour du
+pic. Le but est de généralisé les tests de millets pour qu'ils se
+ressemblent le plus possible.

+
+On retrouve les trois fichiers permettant de classifier la base ICDAR
+en trois sous populations. Le test de saturation consiste simplement à
+regarder si une certaine quantité de la population de l'histogramme de
+saturation est en dessous d'un certain seuil. La généralisation du
+test ne porte pas sur le test en lui-même, mais sur la forme dans
+lequel le test est fait.

+
+
+Le test de value a déjà été décrit précédemment dans
+stddev_color. L'idée est toujours la même, mais cette fois il est
+effectué dans l'espace des valeurs (HSV). Cela ne change pas grand
+chose, puisqu'il était utilisé sur des images en niveau de gris. C'est
+l'un des tests importants car il réagit à la différentiation entre une
+image type photographie et une image plus stylisée comme un
+clipart. Ce test a aussi des vertus pour la distinction entre du noir
+& blanc et de la couleur. Il s'avère que les images type photographie
+avec pleins de couleurs ont un histogramme moins sujet aux pics que
+les histogrammes noir & blanc. De facto, l'énergie de l'histogramme
+est distribué sur l'ensemble de la plage contrairement aux images noir
+& blanc où il y a une concentration de chaque côté de l'histogramme
+(bipolarité).
+
+* exp/annotating/value: Implémentation de la généralisation du test de Millet.
+* mln/fun/v2v/rgb_to_value_map.hh : Transformation d'espace.
+
+
+Le programme hsv reprend les tests préalablement élaborés auparavant
+sur les plans H, S puis V. Il combine tout en un seul programme pour
+avoir une vision plus synthétique de ce qui se passe sur les 3 espaces
+simultanément.
+
+Les tests incorpore mes transformations. C'est à dire que l'on
+effectue une série de test équivalent à ceux de Millet (au moins dans
+l'idée et le plus souvent, il s'agit d'une réecriture sous une autre
+forme) en partant des histogrammes normalisés. Un histogramme
+normalisé est un histogramme de flottant qui contient l'histogramme
+classique divisé par le nombre total de pixels. En faisant cela, on se
+déplace dans l'espace des distributions. Si l'histogramme n'a qu'un
+seul pic et que ce dernier contient tous les pixels (pic de dirac par
+exemple), alors l'histogramme normalisé donnera 1 comme valeur de
+proportion à ce pic. En fait, l'intégrale d'une distribution vaut
+1. Le but des distributions est de s'affranchir des caractéristiques
+de taille de l'image, ce qui permet de comparer les histogrammes entre
+eux. On peut ainsi comparer les histogrammes d'une photo AFP petit
+format avec celui d'une image grand format de la base ICDAR. Le but du
+jeu est de garder les idées de Millet dans ce nouvel espace. Les tests
+obtenus sont équivalents mais pas identiques.
+
+Pour la teinte, une fois l'histogramme normalisé obtenu, on cherche à
+savoir s'il existe un pic avec une forte proportion de l'histogramme
+autour de ce pic. Plutôt que le pic, nous prenons la moyenne qui est
+un opérateur un peu plus robuste et nous calculons la proportion de
+l'histogramme autour (un seuil donné en paramètre défini le périmètre
+du calcul). L'expression sous forme de proportion plutôt que sous la
+forme d'une variance rend le test homogène avec les autres tests.
+
+Pour la saturation, après normalisation, on regarde la proportion de
+l'histogramme en dessous d'un certain seuil. Il n'y a pas de
+changement significatif par rapport au test de Millet. Le seuil
+initialement proposé par Millet était 100, il a été adapté car nos
+bases sont différentes des siennes (le notre est à 25).
+
+Le test sur les valeurs (cliparts contre photos) a vraiment un intérêt
+au delà de ce cas d'utilisation. Il nous renseigne sur la
+concentration autour d'un pic de l'histogramme ou non. Nous préferrons
+la mesure de similarité à l'équi-répartition des densités, mais l'idée
+est exactement la même. Est-ce que notre histogramme est plat ou
+inversement, est-ce que les contributions sont rassemblées autour d'un
+pic? Si une image est noir et blanc, il existera un pic correspondant
+au fond et la densité s'éloignera fortement de la distribution
+équiprobable. Dans le cas maintenant d'une image couleur, la
+répartition est plus homogène, couvrant un large spectre dans le
+domaine de l'histogramme. Du coup, la distribution semblera davantage
+equi-répartie. On notera que nous prenons le test à l'envers de ce que
+propose Millet. Il essaye de voir si il y a un pic et calcule une
+forme de contribution normalisée autour de ce pic. Nous au contraire,
+on regarde l'absence de pic et on calcule la différence entre la
+densité et cette absence de pic. Notre avantage par rapport à Millet
+est démontré particulièrement dans les cas où il existe plusieurs
+grosses distributions. A contrario, notre test souffre des cas où il
+existe de nombreuses petites distributions.
+
+
+Voici un premier retour sur les expériementations:
+La discrimination entre la base AFP et la base ICDAR peut se faire en
+étudiant la forme des densités des niveaux de gris. Les images
+naturelles semblent avoir un spectre recouvrant en général les 256
+niveaux de gris alors que les images de documents ont une présence
+importante du fond. Dans le cadre d'une densité, ce qui est alloué sur
+le fond ne peut se retrouver ailleurs. Une comparaison avec la densité
+équiprobable nous renseigne donc sur la nature des images. Il semble
+néanmoins qu'un certain nombre d'images défient ce dispositif. Par
+exemple des gros plans sur des zones mono-teintée (ski, voile,site
+web).

+* mln/fun/v2v/rgb_to_value_map.hh : Transformation d'espace.
+
+
+Le test sur l'achromatisme des images est décrit dans le code
+suivant. Il a été purement et simplement abandonné dans la mesure où
+c'est un cas très particulier qui est repris par une saturation très
+faible. La saturation s'exprime comme 1 - min(channel)/max(channel),
+mais dans le cas où le min(channel) == max(channel), la saturation
+vaut 0. Le problème vient plutôt du calcul de la teine qui ne peut pas
+admettre que le min soit égal au max. Pour ce calcul, on se débrouille
+pour gérer le cas et renvoyer une valeur standardisée, Millet
+proposait -1.

+
+
+Ce programme a pour but de créer les histogrammes normalisés en rafale
+pour les bases AFP et ICDAR. Il assure leur création dans les six
+plans possibles R,G,B,H,S,V. De cette manière il est possible de
+vérifier les corrélations éventuelles entre le canal B et G. Par
+ailleurs, après visionnement de tous les histogrammes, on note des
+spécificités dans les deux bases sur les plans S et V. Certaines
+images ont des réactions très fortes sur le plan H, mais ce n'est pas
+une caractéristique pour une base (seulement pour ces images en
+question). Les résultats ont déjà été sauvegardés dans le répertoire
+image du LRDE. Des infos sont notés à ce sujet dans README.result. Le
+seul but de ce calcul est de maîtriser csujet dans README.result. Le
+seul but de ce calcul est de maîtriser ce qui se passe dans ces
+espaces, pas simplement de supposer ce qu'il pourrait s'y passer. La
+comparaison des images est rendu possible quelque soit la base
+d'origine par le fait qu'elles sont normalisées. Chaque fréquence des
+histogrammes est divisée par la somme des fréquences. On obtient donc
+une version discrète des densitées. La somme des nouvelles fréquences
+vaut 1. On voit davantage si les densités se rapprochent d'une
+équi-répartition ou non. La négative implique un ou plusieurs pics. Le
+cas défavorable dans mon approche (qui existe pour certaines images)
+est une multitude de tout petits pics autour de l'équi-répartition. Ce
+n'est pas équi-répartie pour les calculs mais ce n'est clairement pas
+la manisfestation d'une concentration de l'énergie quelque part.

+
+
+Dans le programme erreur, on teste l'idée de jonathan. Une référence à
+ce sujet peut être trouvée dans README.img. Les bases AFP et ICDAR
+sont retravaillées à l'aide de ImageMagick et de Gimp pour diminuer le
+nombre de couleurs initiales. On oblige à n'avoir que 30, 20 ou 10
+couleurs pour chaque base. Il y a donc 4 versions de chacune des bases
+en comptant la version originale des images. Les algorithmes utilisés
+par Gimp et ImageMagick sont très différents. L'idée de Jonathan était
+de dire que lorsqu'une image est couleur, plus on réduit le nombre de
+couleur, plus elle change vis-à-vis de l'image originale. Inversement,
+si une image possède peu de couleurs (noir & blanc), sa dégradation ne
+l'altérera pas tant que cela. Prenons une image d'un skieur de la base
+AFP, en réduisant le nombre de couleurs, la combinaison marron va
+devenir marron strictement homogène et la perception que nous en avons
+est visuellement très altérée. A contrario, une image en noir & blanc
+ne semble pas bouger d'un pouce. La comparaison avec la discrimination
+sur la saturation ou la valeur montrera des résultats un peu meilleur
+plus tard mais il impossible de préjuger a priori des résultats
+futurs. L'erreur entre l'image initiale et l'image dégradée est
+calculée avec le PNSNR (compression p278 Handbook Color). Le programme
+calcule la dégradation et essaie de trouver automatiquement des seuils
+de séparation pour les deux bases. 4 détection de seuils sont testées.
+Ces seuils sont calculées avec deux bases représentatives des bases à
+discriminer. En mode production, le seuil est vu comme une constante
+pour le programme. Les deux premières classifications renvoient un
+seuil calculée comme une moyenne pondérée des moyennes des populations
+à discriminer. Le premier détecteur pondère par la déviation standard
+et le second par la variance. Le troisième simule deux populations
+gaussiennes de variances différentes et résoud l'équation de second
+degré qui en résulte. Enfin, le dernier test ne préjuge pas des
+distributions statistiques et réalise la minimisation de l'erreur de
+classification. Pour cela, il suffit de compter le nombre d'images
+bien classées et mal classées sur les bases d'apprentissage des
+populations. On utilise pour cela la méthode Otsu. Le détecteur PNSRN
+renvoie une valeur. Pour chaque population (AFP, ICDAR), on construit
+l'histogramme de des valeurs obtenues. A noter, qu'il faut que les
+valeurs du PNSNR soient ramenées entre 0 et 255. En pratique ce n'est
+pas un problème, mais il faut le mettre en oeuvre, dans mon code, ce
+n'est pas fait (les valeurs ne posaient pas de problème). Donc, pour
+chaque seuil possible (de 0 à 256), on étudie la matrice de classement
+(groupe 1 - détecté groupe 1, groupe 1 - détecté groupe 2, groupe 2 -
+détecté groupe 1, groupe 2 - détecté groupe 2). L'erreur est
+simplement la somme des quantités groupe x - détecté groupe y avec x
+!= y. Finalement, pour chaque seuil, il est possible de connaitre
+l'erreur. Le processus de minimisation de l'erreur revient à chercher
+le seuil associé à l'erreur minimale. C'est ce dernier test que nous
+préconisons. Il faut mettre en lumière que ces quatre tests renvoient
+à peu près les mêmes seuils. La minimisation de l'erreur étant le
+meilleur de tous puisqu'il minimise directement l'erreur de
+classification et c'est ce que nous cherchions en fin de compte. Un
+cinquième test a été fait avec une analyse de fisher sur l'histogramme
+des populations mélangées, mais c'est une idée saugrenue car nous
+disposons à ce niveau des populations séparées et évidemment les
+résultats sont moins bons.
+
+Petit rappel. Un vieux problème a été mis à jour ici. Lorsqu'on
+calcule des informations sur un histogramme, le type temporaire qui
+contient les résultats ne doit pas être le type qui encode les valeurs
+des résultats. Par exemple, un histogramme de byte, un calcul de
+variance tout simple où il faut stocker la valeur des pixels au carré
+multiplié par leur occurrence tiendra facilement dans un long mais pas
+dans un byte. Le sucre avec les acesseurs des itérateurs tend à
+mélanger les genres. Une solution simple est de stocker la valeur de
+l'histogramme dans un type pouvant effectuer les calculs et ensuite
+retravailler avec ce type. Nous avions déjà discuté de ce problème et
+je ne sais pas si tu avais pu corriger le problème. Si la
+classification renvoit n'importe quoi, il se peut que cela provienne
+de ce problème. Le problème ne se voit pas sur des calculs de
+moyennes, il ne s'observe que sur certains calculs de variance (dépend
+de la formule utilisée).
+
+* exp/annotating/error: Test de l'idée de jonathan (dégradation des couleurs)
+
+
+Le travail dans bench.cc reprend toute sorte de travaux déjà réalisés
+dans d'autres fichiers. Il a pour but de comparer ensemble tous les
+descripteurs pour la reconnaissance de base de données entre l'AFP et
+l'ICDAR.
+
+Le travail commence avec un certain nombres de routines travaillant
+sur les histogrammes permettant de trouver le pic, la moyenne, la
+variance et d'autres éléments. Les routines étaient éparpillées dans
+le code, du coup je les ai regroupées au même endroit. Il y a des
+redondances de code correspondant à des copier/coller ou à différents
+essais. Prendre les versions les plus génériques et en faire des
+accumulateurs serait un riche idée.
+
+Huit détecteurs sont comparés ensembles:
+- hue1, détection d'un pic de teinte très dense par la méthode de Millet.
+- sat1, détection d'une densité importante dans les saturations basses (Millet).
+- lvl0, comptage du nombre de niveau de gris (idée de Millet).
+- hue0, détection d'un pic de teinte par la méthode des densités.
+- sat0, détection d'une forte basse saturation par la méthode des densités.
+- val0, détection d'un pic de niveau de gris par la méthode des densités.
+- val1, détection d'un pic de niveau de gris par la méthode de Millet.
+- err, PNSNR (idée de jonathan).
+
+FIXME: Attention, le PNSNR n'est pas borné, il faut le faire, il doit avoir
+au maximum 255 comme valeur.
+
+Tous les détecteurs ont été expliqués en large, en long et en travers
+dans les sources précédentes. LIRE le chapitre XII (ANNOTATING) de ce fichier
+en entier.
+
+Ensuite vient les séparateurs de population statistiques qui ont été
+déjà introduit dans le fichier error. Bien que tous soient présent,
+c'est la minimisation de l'erreur qui est utilisée.
+
+Enfin vient le front end, l'un des plus complexes que j'ai écrit cette
+année. Le main lui même, n'est pas la partie la plus complexe. Il
+définit les actions fonctionnelles à réaliser et la structure de
+donnée réalisée pour garder la trace de tous les résultats.
+- File_name : Cette variable retient le nom des fichiers. C'est un tableau
+de la taille du nombre d'images rencontrées toute base confondue. Comme on
+ne parcourt qu'une fois les répertoires, il faut pouvoir retenir cette
+information qui servira éventuellement pour la nomenclature des dumps
+par la suite.
+- Result : Cette variable contient toutes les informations du traitement.
+C'est un tableau à deux dimensions, une pour les images et une autre pour
+les descripteurs. L'index d'image est le même que pour file_name.
+- Size : Cette variable contient le nombre d'images par database.
+- Threshold : Cette variable va stocker les seuils calculés sur chacun
+des descripteurs. Ces seuils sont sensés effectuer la séparation entre les
+deux bases.
+- Cxx : variables de comptage des images bien ou mal classées relativement
+à la position des seuils et à l'appartenance d'origine des images. Cette
+appartenance d'origine est calculée à l'aide Size qui contient le nombre
+d'image par base de données. Comme les images sont vues dans l'ordre, les X
+premières appartiennent à la base ICDAR et les Y suivantes à la base AFP.
+- histo : Variable servant à effectuer par database et par descripteur un
+histogramme utilisé ensuite lors de la discrimination des bases.
+
+La partie compute_descriptors a pour mission de passer une fois sur
+toutes les images et de calculer les descripteurs associés. A l'issue
+de cette passe file_name, result et size sont remplis et pourront être
+utilisés par les autres routines.
+
+La partie dump_descriptors a pour but de réaliser un tracé en gnuplot,
+avec une couleur différente pour chaque base. Le graphe montre les
+valeurs utilisées par chaque descripteur pour toutes les images de la
+base.
+
+La partie correction des descripteurs est optionnelle et force un
+certain nombre de valeurs pour être inférieures à 256. Le but était de
+pouvoir travaillé, même si les descripteurs n'étaient pas complètement
+opérationnels. Elle sert donc pour le debug.
+
+La partie calcul des histogrammes sert à obtenir la distribution des
+valeurs de chacun des descripteurs en fonction des bases
+utilisées. C'est une étape préliminaire à l'analyse des populations et
+au calcul des seuils.
+
+La partie calcul des seuils repose sur la minimisation des erreurs de
+classification. Cette méthode ne fonctionne bien si la classe zéro à
+une moyenne inférieure à la classe un. Du coup, il n'est pas possible
+de déterminer de manière simple si la classe 0 correspond à l'AFP ou à
+l'ICDAR. Pour chaque descripteur, les cartes sont rebattues.
+
+Enfin, tous les histogrammes sont sauvés pour pouvoir comprendre et
+visualiser les résultats.
+
+Le main2 ne sert à rien, juste pour des essais.
+
+Attention, modification VAL0/VAL1, vérifiez que le bon descripteur est
+au bon endroit dans le tableau.

+/// \brief The main entry and the whole processing routine
+///
+/// This is the routine which works on Millet test. First compute the
+/// achromatic mask. Then build the transfer between RGB and HSV. Then
+/// isolate each channel to work on it. Each separate channel is bound
+/// between 0 and 255. Then keep only pixels low saturated (< 100 in S
+/// canal) in a specefic map. Build the 3 histograms without the
+/// achromatic pixels based on the 3 separated channels (H/S/V). Build the
+/// 3 maps (hue_concentration, low_saturation and achromatism). Then do
+/// the 3 tests of Millet with the thow thresolded pass (threshold,percentage).

+/// \brief Implement the Millet clipart detection [millet.phd.2008.pdf]
+///
+/// The aim of this descriptor is to recognize clipart. To do this, we
+/// assume that clipart have their histogram concentrated around their
+/// mode. This is particularly true if the clipart is design by hand,
+/// because a very small number of grey tones or colors are used to
+/// draw it. But sometimes, computer assists their creation and we can
+/// find some continuous set of tones and this artefact create noise
+/// for the detection technique describe bellow. When photographies
+/// has some large uniform border, the detection can fail. To improve
+/// the method, Millet decide to subdivise the image in 16 sub images
+/// on which it applies the test.

+/// quality. The PNSNR detector is build and learning threshold for

+/// \brief Implement the Millet clipart detection [millet.phd.2008.pdf]
+///
+/// The aim of this descriptor is to recognize clipart. To do this, we
+/// assume that clipart have their histogram concentrated around their
+/// mode. This is particularly true if the clipart is design by hand,
+/// because a very small number of grey tones or colors are used to
+/// draw it. But sometimes, computer assists their creation and we can
+/// find some continuous set of tones and this artefact create noise
+/// for the detection technique describe bellow. When photographies
+/// has some large uniform border, the detection can fail. To improve
+/// the method, Millet decide to subdivise the image in 16 sub images
+/// on which it applies the test.

Ce travail m'avait été demandé par théo. Je le laisse inachevé, quelque part
perdu pendant l'optimisation du code et sa transformation en canevas.
+
+a) Première implémentation avec matrices et vecteurs
+
+Cette version est bien documentée et permet de mieux comprendre les autres
+versions. Par ailleurs, elle n'est pas spécialement optimisée ce qui fait
+qu'elle colle davantage au modèle de l'algorithme kmean traditionnel.

+* tests/clustering/k_mean: Tests unitaires sur la permière version.
+
+
+b) Seconde implémentation avec image en 1d
+
+Cette seconde version intègre une optimisation testée par théo il y a
+longtemps. Je me demande si ce n'étais pas pendant sa thèse qu'il
+avait travaillé sur cette version. Bref, dans la mesure où
+l'optimisation passe par la création d'un histogramme, cette version
+devient dépendante des histogrammes réalisés plutôt (il est aussi
+dépendant de la sauvegarde au format gnuplot shell). L'idée générale
+de l'optimisation est de ne plus raisonner sur l'image, mais sur
+l'histogramme. Car à un moment donné, la classification ne tient
+compte que de la valeur du pixel en intensité (pas de ses coordonnées
+dans l'image). Donc tout pixel de même intensité sera classé de
+manière identique. D'où l'intérêt de travailler avec les
+histogrammes. Les limites de cette optimisation se trouvent dans la
+taille des histogrammes. L'optimisation marche à merveille pour de
+faibles quantifications (8 bits c'est parfait). Par contre, lorsque
+l'on passe à un histogramme couleur, la taille de l'histogramme
+devient problématique et peut dépasser la taille de l'image. Cette
+optimisation n'a alors plus aucun sens.

+
+La visualisation de la convergence des moyennes, générée par le
+démonstrateur, n'est pas très lisible. La lecture textuelle du fichier
+gnuplot shell (mean_cnv.sh) permet d'interpréter ce qui se passe, par
+contre le graphique est à refaire.
+
+
+c) kmean2d
+
+Cette troisième version est identique à la seconde, sauf qu'elle
+permet de faire la classification dans un espace à deux
+dimensions. Malheureusement, un tel travail dans cet espace coûte
+beaucoup plus cher à l'exécution.

+La visualisation de la convergence des moyennes est cette fois-ci
+complètement aboutie. Le fichier semble avoir quelques soucis, il
+manque des lignes dans le splot initial, en remettre pour qu'il y en
+ait autant que les blocs de données. L'espace des couleurs étant le
+bicanal r/g, on peut visualiser sur une troisième dimension
+l'évolution des centres dans l'espace initial. L'effet est très réussi
+et aussi très parlant. Chaque run, correspond alors à une trajectoire
+particulière. L'affichage des variations des variances a été rénové et
+est lui aussi beaucoup plus lisible.
+
+
+d) kmean3d
+
+Cette quatrième version est la copie conforme de la version
+précédente. Les problèmes de visualisation sur les fichiés générés
+sont les mêmes. L'affichage des convergences est identique. Le recours
+à une dégradation de l'image d'entrée est impérative pour avoir des
+temps encore acceptables.

+
+
+e) kmean aplati
+
+Cette cinquième version est très spéciale. Elle doit permettre de
+gagner du temps d'exécution. Le concept est simple au départ, tout
+écrire d'un seul tenant. L'exercice est fastidieux et difficile
+(intellectuellement). Une fois fait, il faut réfléchir à ce qui peut
+être mis sous forme de canevas. Par exemple, la manière de calculer
+les distances peut être une information paramétrable. Cela pemettrait
+de faire un benchmark in situ. La transcription actuelle compile. Elle
+n'intègre pas tous les outils de debuggage que nous pouvions avoir sur
+les autres versions. Par ailleurs, comme le code est réuni en une
+seule fonction, nous avons pour l'instant une seule sortie, l'image de
+labels de la classification réalisée. A partir de cette image, nous
+pouvons en reconstruire d'autres. Il manque quand même la possibilité
+d'observer les convergences. Le travail était en cours, à prendre donc
+avec beaucoup de pincettes. La dernière exécution house.ppm, 3
+centres, 10 itérations et 10 runs fonctionne parfaitement sur les
+premiers runs puis l'affichage s'emballe sans que l'on y comprenne
+rien. Un dump dans un fichier révèle le non appariement de certaines
+traces (entering/exiting). Une piste à suivre est la sortie anticipée
+d'une de mes boucles sans pour autant fermer une trace ... ???

+
+f) optimisation possible
+
+Le calcul des distances entre les points et les différents centres
+peut être réalisé par des transformées. Certes, les distances ne seront
+pas les mêmes que la distance euclidienne, mais elles s'en approchent
+et cela constitue très certainement une très bonne approximation pour
+l'objectif que nous cherchons à atteindre. Le but de ce benchmark est
+de regarder quel type de transformation est le plus rapide pour
+arriver à nos fins en fonction des données d'entrée. Cette
+optimisation n'a pas encore été intégrée dans le code, et reste une
+piste à exploiter.
+
* bench/clustering/distance: Comparaison algorithmes d'évaluation des distances.
-==> to do
+Une routine du benchmark ne compile plus. Il semble qu'il y ait un
+mauvais appel à la fonction at_ dans la routine
+influence_zone_geodesic.hh ligne 127. Le but du benchmark est de
+tester les distances en 2d et 3d pour des voisinages différents (c04,
+c08, c06, c18, c26) sur les routines distance euclidienne classique,
+zone d'influence geodesique et zone d'influence "front". La première
+serie de test vise à garder une taille d' image constante et
+d'augmenter le nombre de centres pour voir comment se comporte les
+algorithmes et la seconde serie, vise à garder un nombre constant de
+centres et à agrandir progressivement l'image. Attention, le benchmark
+essaye d'être assez exhaustif et donc se paye par un temps d'execution
+assez long. Les différents fichiers générés reprennent les différents
+tests effectués et montrent l'évolution du temps de calcul suivant la
+progression du paramètre observé (taille de l'image ou nombre de
+centres).
+
+==> to do : le changelog + commit + give it to scribo-z branch

+/// looks after the influence geodesic, the influence front and
+/// euclidian distance. Many files are generated. Some rules exist to
+/// build the name of the file:
+/// distance.neighbouring.dimension.(size|seed). The distance could be
+/// the front distance (front), the geodesic distance (geodesic) or
+/// the euclidian distance (euclidian). The neighbouring could be c04
+/// or c08 in 2d, c06, c18 or c26 in 3d. The dimension could be 2d or 3d.
+/// Finally, the flag size or seed precises the nature of that test, increasing
+/// gradualy the size of the image or increasing gradualy the number of seeds.
+/// The file contains the time benchmark of the distance studied.
+///

+/// center. It's quit easy with xv, to transform the label image in
+/// the color one. The file "mean.pgm" replaces each label by the mean
+/// of the points that contributate to their center. It is a kind of
+/// abstraction of the reality of the image, of its complexity. In
+/// file "variance_cnv.sh" abscissa axis stands for the convergence
+/// evolution and the ordinate axis for each runs. The "mean_cnv.sh"
+/// file shows the evolution of the centers, whatever the run. The
+/// x-axis represents the id of the center, the y-axis the iteration
+/// in the convergence process and the z-axis the id of the particular
+/// run. The graphic is very bad, but textual interpretation is still
+/// available.

+/// \brief This is a demonstrator for kmean3d.
+///
+/// The demonstrator produces five kind of results. The file
+/// "color.ppm" allow us to localize the different center in the
+/// image. There is an equivalent file "label.pgm" that's do the same
+/// thing but inplace of a specific color, it gives the label of each
+/// center. It's quit easy with xv, to transform the label image in
+/// the color one. The file "mean.pgm" replaces each label by the mean
+/// of the points that contributate to their center. It is a kind of
+/// abstraction of the reality of the image, of its complexity. The
+/// "variance_cnv.sh" changes its representation and becomes more
+/// readable. The "mean_cnv.sh" have got a generation problem. We can
+/// bypass it by adding printing lines in the 'splot'
+/// instruction. However, the graphic is correct and mainly shows the
+/// convergence of the center value.

-Le travail est classé dans deux répertoires ok et ko.
-Le répertoire ok correspond aux sources qui ont été reprises et retestées.
-Le répertoire ko correspond aux sources qui ont été juste transférées.
+I ARBORESCENCE
+--------------
-La première brique logicielle importante sur laquelle s'appuie mes travaux est
-la création d'histogrammes sous forme d'image.
+bench ==> Comparaison d'algorithmes d'un point de vue temps d'exécution.
+bug ==> Bug rencontrés dans milena et archivés sous forme de programme.
+build ==> Répertoire d'exécution, non sauvé dans git.
+demo ==> Première version d'un algorithme pour voir son comportement.
+doc ==> Documentation tex ou code minimal pour de petits exemples.
+exp ==> Version avancée des algorithmes pour traitées les bases de données.
+mln ==> Partie mise en librairie milena des différents travaux.
+tests ==> Tests unitaires sur certains algorithmes.
+tools ==> Découpage de certains algorithmes pour mieux les tester séparément.
+use ==> Test de compilation, code minimal pour compiler un élément.
+II COMPILATION
+--------------
-CREATION DES HISTOGRAMMES
--------------------------
+L'unité minimale de code choisie est le répertoire.
+Donc aller dans le répertoire qui nous interesse,
+par exemple, green/demo/annotating/hsv et lancé le make
-ko/mln/accu/stat/histo1d.hh: histogramme image valeur scalaire.
-ko/mln/accu/stat/histo2d.hh: histogramme image valeur vectorielle 2d.
-ko/mln/accu/stat/histo3d_hsl.hh: histogramme image valeur vectorielle 3d (HSL).
-ko/mln/accu/stat/histo3d_rgb.hh: histogramme image valeur vectorielle 3d (RGB).
+#:~/git/olena/scribo/sandbox/green$cd demo/annotating/hsv
+#:~/git/olena/scribo/sandbox/green/demo/annotating/hsv$ make -f Makefile.am
+Cette opération créé dans build le répertoire de compilation
+green/build/demo/annotating/hsv. Dans ce répertoire aura été copié un
+Makefile et tous les fichiers qui ne sont pas des sources. Par
+exemple, des fichiers de calibration comme gaussian.sh (pour vérifier
+la mire du filtre de gaussienne) ou de la documentation à la sauvette
+sous forme de fichiers textes jetés à la va vite dans le répertoire
+pour ne pas perdre l'information recherchée. En l'occurence, ici, il
+n'y a rien à copier. Rendons-nous dans le répertoire de compilation et lançons
+le makefile.
+#:~/git/olena/scribo/sandbox/green/demo/annotating/hsv$
+cd ../../../build/demo/annotating/hsv
+#:~/git/olena/scribo/sandbox/green/build/demo/annotating/hsv$ make clean all
-ok/mln/accu/histo/histo1d.hh: histogramme image valeur scalaire entière.
-ok/mln/accu/histo/histo2d.hh: histogramme image valeur vectorielle 2d entière.
-ok/mln/accu/histo/histo3d.hh: histogramme image valeur vectorielle 3d entière.
+L'exécutable est généré par le makefile, il porte le nom du
+répertoire. Si il y a besoin de mettre à jour le makefile, le faire
+dans le répertoire des sources en éditant Makefile.am, puis en
+régénérant le Makefile dans le répertoire d'exécution par la commande
+make -f Makefile.am depuis le répertoire source.
-SAUVEGARDE DES HISTOGRAMMES
----------------------------
+III MAKEFILE
+------------
+Les makefiles utilisés sont tous les mêmes avec quelques variables
+dont le contenu change dans leur partie en-tête.
+Pour chaque répertoire, le makefile doit savoir si le chemin courant
+est un répertoire de compilation ou un répertoire de source. Pour les
+identifier, il a recours à un pattern qui malheureusemnt fait
+intervenir le nom de la branche de développement (bench,demo,bug,exp ...).
+SOURCE_PATTERN= green/demo
+BUILD__PATTERN= green/build/demo
-VISUALISATION DES HISTOGRAMMES
-------------------------------
\ No newline at end of file
+Si un makefile ne fonctionne pas, il faut vérifier ceci en premier
+lieu. Ici, le makefile doit être situé dans la branche démo.
+
+Autre élément à savoir, la compilation nécessite d'inclure la
+librairie milena, ainsi que les développements propres en vu de leur
+intégration futur dans milena, ceci est fait par un jeu d'INCLUDES1
+et INCLUDES2.
+
+INCLUDES1= -I$(HOME)/git/olena/scribo/sandbox/green
+INCLUDES2= -I$(HOME)/git/olena/milena
+INCLUDES= $(INCLUDES1) $(INCLUDES2)
+
+Suivant l'allure du compte où l'on exécute les makefiles, il faut
+revoir le chemin pour trouver des deux répertoires.
+
+Enfin, les options de compilations ne sont pas toujours les mêmes. Les
+trois lignes possibles sont toutes présentes et seule celle qui est
+utilisée n'est pas commentée. Typiquement, dans la branche de
+développement démo où les perfomances ne sont pas le problème, on
+compilera avec tout le matériel pour utiliser gdb et sans
+optimisation. A l'inverse, dans la branche d'expérimentation, où le
+code a déjà été testé, on cherche à aller vite car on exécute ce code
+sur de nombreuses images. Dans cette optique, pas de débugage, pas de
+traçage, optimisation conséquente.
+
+CXXFLAGS= -ggdb -O0 -Wall -W -pedantic -ansi -pipe $(INCLUDES)
+#CXXFLAGS= -DNDEBUG -O1 -Wall -W -pedantic -ansi -pipe $(INCLUDES)
+#CXXFLAGS= -DNDEBUG -O3 -Wall -W -pedantic -ansi -pipe $(INCLUDES)
+
+Une dernière dernière information, dans le cadre des développements
+exp, et tools, on utilise la librairie boost soit pour la
+virtualisation du filesystem, soit pour le formatage des fichiers text
+(réalisation de colonnes, mettre des entiers sur un certain nombre de
+caractères). Une ligne de chargement des librairies peut apparaitre donc.
+
+LOADLIBES= -lboost_filesystem
+
+On retrouvera les includes suivantes dans les sources:
+
+#include <boost/format.hpp>
+#include <boost/filesystem.hpp>
+
+
+IV CHEMINS DES IMAGES
+---------------------
+
+Toutes les images ont toujours été locales sur mon ordinateur. La
+politique a toujours été d'utiliser un fichier img_path pour coder les
+chemins des images. Les chemins étant plutôt long, j'ai toujours eu
+tendance à faire en sorte qu'ils soient compilés en dur (sauf pour la
+partie développement tools qui est vraiment voué à donner des
+exécutables indépendants et génériques). Le fichier mln/img_path.hh
+code la position de toutes les images dans mon arborescence. Il faudra
+donc veiller à changer tous les chemins pour les adapter au compte
+dans lequel on voudra reprendre le code. Dans le code, les références
+aux positions des images sont faites via des macros.
+
+Toutes les images sont située dans git/img. En règle générale, je ne
+traite que des images au format .pgm, .pbm et .ppm. Il m'arrive
+fréquemment de dumper des images au format .sh (gnuplot shell
+image). Pour la branche tools, nous avons utilisé les dumps de milena
+comme format de transfert d'un utilitaire à un autre. Les images sont
+classées suivant leur provenance. Nous avons tout d'abord la base
+OLENA (copie des images de tests milena), la base INIM (très peu
+utilisée voire jamais), la base ICDAR (très utilisée, surtout dans
+exp), la base AFP (très utilisée dans exp) et les bases ANNOTATING1 et
+ANNOTATING2 (pas très utilisées ni l'une, ni l'autre).
+
+La plus part du temps, sauver les résultats dans le répertoire
+d'exécution courant est largement suffisant. Parfois, il est

+V GNUPLOT SCRIPT SHELL IMAGE FORMAT
+-----------------------------------
+
+J'abrège le nom du format par gnuplot shell format. En fait, c'est un
+format d'image particulier qui a besoin de gnuplot pour être lu. Il
+est donc compatible avec aucun viewer si ce n'est gnuplot, mais a la
+caractéristique d'afficher tous les points de manière visible. Par
+ailleurs, comme il s'agit d'un script gnuplot il permet d'insérer très
+facilement une fonction pour visualiser les données autrement (par
+exemple, changer d'espace: HSL, HSV). Le fichier tire son nom de la
+façon dont il fonctionne. C'est un script shell qui fait un appel à
+gnuplot et lui passe le jeu de données directement à partir de ce même
+fichier, pas besoin de faire appel à un autre fichier. Une fois
+généré, le fichier doit être modifié pour avoir les permissions
+d'exécution (chmod 755 gnuplot_shell_file.sh). Comme je trouve le format
+extrêmement pratique, il se retrouve preque partout dans mes sources.

+
+Un des travaux demandés par théo est la réalisation d'une librairie
+d'histogramme permettant de fournir un résultat sous forme d'image.
+L'intérêt est ensuite de pouvoir filtrer directement ces histogrammes
+par les algorithmes de milena, ou encore d'étudier les valeurs
+caractéristiques par d'autres accumulateurs. Les codes réellement
+utilisés sont histo1d et histo3d RGB. Tous les autres codes sont très
+expérimentaux. Notemment, le code HSL demande de quantifier l'espace
+de comptage puisqu'il est décrit sous la forme de triplets de float
+(les autres sont inférés). Néanmoins, le code est à conserver car il
+contient une séquence d'appels pour les routines permettant de
+considérer la dimension de la teinte comme circulaire.

+/// This source implements the discrete histogram version. It was

+/// int_u<14> image has got 16384 bins. But, this code doesn't work
+/// for that quantification because of the coord limitation (signed
+/// short, as it is defined in mln/core/def/coord.hh). Take care of

+/// of values. Do not use it outside this purpose, i can't garantie
+/// the behaviour.
