Un coup de Sobel 3x3, puis une +binarisation avec s=100. On considère les moitiées verticales puis +horizontales. Pour les moitiées verticales, on réalise la somme sur chacune +des lignes, on obtient alors un vecteur de taille 100. +Pour les moitiées horizontales, on réalise les sommes des colonnes. On obtient +alors un vecteur taille 100. Les 4 sous vecteurs obtenus peuvent être +concaténés pour former un unique descipteur de 400 composantes. + + + +ANNEXE 2 : SYNTHESE CLASSIFICATION MILLET +========================================= + + +* Reconnaissance des images de clipart versus photographies +----------------------------------------------------------- + +Construire l'histogramme de l'image, éliminer toutes les couleurs peu +représentées et ensuite les comptées. Moins de 50 couleurs / 256, c'est un +clipart, plus de 150 / 256 c'est une photographie. Entre les deux, indécision. +D'après l'auteur, le test n'est pas complètement fiable et peu être évincé, tout +dépend de la qualité de la compression des cliparts. + +Diviser l'image en 16 imagettes (4x4), calculer la suite pour chaque imagette. +Trouver le maxima de l'histogramme (noté p)/ p = argmax H(x), x in [0,255]. +Puis on calcule un sigma autour du pic. + +sigma^2 = Sum(p-1,p-5) r(x) pour p > 250 +sigma^2 = Sum(p+1,p+5) r(x) pour p < 005 +sigma^2 = (1/2) (Sum(p-1,p-5) r(x) + Sum(p+1,p+5) r(x)) pour les autres p + +r(x) = ((H(x)/H(p)) * (x-p))^2 + + +Le descripteur de l'image entière est alors le maximum des 16 sigma^2. Si le +pic est resseré, c'est plutôt un clipart (< 5), sinon plutôt une photographie +(> 40). Le seuil est fixé à 15. + + + +* Reconnaissance des images Noir & Blanc versus Couleur +------------------------------------------------------- + +Achromatisme (en passant par TSVal) + +si |R - G| < s +et si |R - B| < s alors R ~ G ~ B +et si |G - B| < s + +==> T = -1 +==> Val = (R + G + B)/3 + +L'auteur propose s = 0,03 + +Une image est dite Noir & Blanc (donc Achromatique) si + de 99% des pixels le +sont. Le test peut être appliqué aux images étiquetées comme des cliparts, ou +des photographies. + + +Faible saturation: + +On établit l'histogramme de la saturation de l'image (0 à 255). Si plus de 95% +des pixels sont inférieurs à une saturation de 100, alors l'image est faiblement +saturée. Ce test ne s'applique sur les photographies, surtout pas aux cliparts. + + +Dominance de la teinte (image jaunie): + +On construit l'histogramme de la teinte (0 à 255). On localise le maximum de +l'histogramme. Si + de 95% des pixels ont une distance < 20 du maximum, alors +l'image est considérée comme Noir & Blanc et on peut donner sa teinte dominante. +De plus il faut qu'au moins 50% des pixels soient faiblement saturés. + +T = -1 Achromatisme + 0 <= T < 14 Rouge + 14 <= T < 29 Orange + 29 <= T < 45 Jaune + 45 <= T < 113 Vert +113 <= T < 149 Cyan +149 <= T < 205 Bleu +205 <= T < 235 Violet +235 <= T < 242 Rose, Magenta +242 <= T < 255 Rouge + + + 0 <= V < 82 Noir + 82 <= V < 179 Gris +179 <= V < 255 Blanc + + +Pour un pixel (S, Val) +si |184 - S| + |65 - Val| < |255 - S| + |125 - Val| alors marron sinon orange. + +Et encore +si la teinte est jaune et Val < 80 alors vert sinon jaune. + + + +* Reconnaissance Interieur versus Exterieur +------------------------------------------- + +Utilisation des descripteurs LEP et RGB-64. Expérience avec un kpp ~ 80%. Puis +expérimentation avec un SVM ~ 90% de réussite. Finalement, inclusion dans le SVM +de LEP, RGB-64, TSVal-125, projection, Bic, Gabor. + + + + +* Localisation des visages +-------------------------- + +Une semaine d'apprentissage, 5 secondes pour leur localisation.

Deux tests sont proposés, le premier est basé sur le +nombre de couleurs de l'image après un seuillage de l'histogramme de +façon à éliminer les couleurs de faible contribution; le second test +consiste à extraire le pic de l'histogramme et à mesurer une +"variance" normalisée autour de ce pic. Le premier test part du +principe que les photographies possèdent de très nombreuses couleurs, +tandis que les cliparts n'en ont que quelques unes. Le test n'est pas +toujours vérifié. Le second test s'intéresse à la nature de +l'histogramme. L'idée étant de montrer qu'un histogramme continu, donc +avec une "variance" élevé autour du pic principal est plutôt +représentatif des phtotographies, alors qu'une "variance" faible tient +d'avantage du clipart (peu de couleurs, couleurs isolées). Selon +l'auteur, ce second test donne de très bon résultats. Il peut être +affiné en divisant l'image en 16 sous parties et en analysant chacune +des imagettes avec la technique décrite ci-dessus.
