Abstract

L'invention concerne une technique robuste permettant de classer automatiquement des images rétiniennes par degrés au moyen de la détection de lésions survenant au début d'une rétinopathie diabétique : petites hémorragies rétiniennes ou micro-anévrismes, hémorragies en taches et en stries, exsudats de lipides et infarctus d'une couche de fibres nerveuses. De plus, l'invention concerne des procédés d'extraction du nerf optique dans les régions convenablement identifiées, et de suivi et d'identification des vaisseaux (par la mesure des diamètres, de la tortuosité et des angles de ramification des vaisseaux). L'invention identifie de préférence 3 niveaux : absence de rétinopathie, micro-anévrismes uniquement, et lésions s'ajoutant aux micro-anévrismes ; les deux derniers niveaux étant les formes de la maladie que l'on peut détecter le plus tôt. Ce procédé permet notamment de surmonter les difficultés posées par la détermination du degré de la rétinopathie, qui sont causées par la variation image à image, le faible contraste de certaines lésions situées à l'arrière-plan, et l'éclairage non uniforme et lumière parasite à l'intérieur de la même image, qui sont à l'origine de la variation dans différents quadrants de la même image. Le système peut utiliser le marquage d'images d'un expert humain et le classement par degrés de la rétinopathie, afin d'améliorer l'évaluation de la qualité de l'image, la détection des lésions et le classement de la rétinopathie.
