Abstract

La présente invention concerne un procédé de mesure de qualité de viande par identification de tissu conjonctif et discrimination des taches de graisse et de sang superficielles présentes. Ledit procédé consiste à générer des images 2D avec éclairage et filtrage à différentes longueurs d'onde soutenu en absorption infrarouge et fluorescence. Des algorithmes de segmentation monochromatique par valeur seuil dynamique sont mis en oeuvre pour la segmentation de tissu avant l'obtention des pourcentages de son contenu.
