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.
