Abstract
Procédé et appareil pour la séparation des couleurs d'une image peinte avec n couleurs distinctes Ci où i va de 1 à n, chaque couleur ayant une distribution spectrale particulière. On sépare en une pluralité de composants spectraux la lumière réfléchie par une surface élémentaire d'une ligne de balayage de l'image. On détermine les intensités x des composants spectraux, on calcule la probabilité P Ci et la fonction p(x/Ci ) de probabilité conditionnelle, on calcule le produit P(Ci )p(x/Ci ) et on détecte la valeur Ci qui maximise le produit P(Ci )p(x/Ci ). L'invention permet d'éliminer les erreurs provenant des informations douteuses sur le spectre de couleur.
