Abstract
A method of classifying an optic nerve cup and rim of an eye from a retinal image comprising receiving a retinal image, determining a feature vector for a candidate pixel in the retinal image, and classifying the candidate pixel as a cup pixel or a rim pixel based on the feature vector using a trained classifier. The retinal image can be a stereo pair, the retinal image can be color or monochrome. The method disclosed can further comprise identifying an optic nerve, identifying an optic nerve cup and optic nerve rim, and determining a cup-to-disc ratio.
