Abstract

L'invention a pour objet de distinguer automatiquement la qualité de la viande avec une grande précision et avec une moindre dépendance envers la main d'œuvre. La solution selon l'invention porte sur un programme de distinction de qualité de viande permettant de distinguer la qualité de la viande, le programme étant caractérisé en ce qu'un ordinateur exécute une étape d'acquisition d'informations consistant à acquérir des informations d'image associées à l'aspect externe de la qualité de la viande à distinguer, et une étape de distinction consistant à utiliser une relation à au moins trois niveaux entre la qualité de la viande et des informations d'image de référence associées à l'apparence externe de la qualité de la viande acquise dans le passé afin de distinguer la qualité de la viande en fonction d'informations d'image de référence correspondant aux informations d'image acquises dans l'étape d'acquisition d'informations.
