Abstract
(EN)
An image processing system for categorising the colour of an item is disclosed. The system comprises processing means configured to: process an image of an item to extract a portion of the image where the item is located; determine a first average colour value of a plurality of colour values associated with the portion of the image where the item is located; map the average colour value to one of a plurality of predetermined colour definitions based on a plurality of colour ranges associated with each colour definition; and categorise the colour of the item according to the mapping.

L'invention concerne un système de traitement d'image permettant de catégoriser la couleur d'un article. Le système comprend des moyens de traitement configurés afin : de traiter une image d'un article permettant d'extraire une partie de l'image où se trouve l'article ; de déterminer une première valeur de couleur moyenne d'une pluralité de valeurs de couleur associées à la partie de l'image où se trouve l'article ; de mapper la valeur de couleur moyenne sur l'une d'une pluralité de définitions de couleurs prédéterminées sur la base d'une pluralité de plages de couleurs associées à chaque définition de couleur ; et de catégoriser la couleur de l'article selon le mappage.
