Patent ID: 8705826

Claim:
A method performed by a computer for obtaining a CDR value from a single 2D retinal fundus photograph, comprising the steps of: (i) receiving, by the computer, the single 2D retinal fundus photograph; (ii) performing, by the computer, optic disc segmentation; wherein said optic disc segmentation comprises deriving an optic disc region of the single 2D retinal fundus photograph received in step (i); (iii) performing, by the computer, optic cup segmentation based on said single 2D retinal fundus photograph; wherein said optic cup segmentation comprises deriving an optic cup region of the single 2D retinal fundus photograph received in step (i); and (iv) inputting data derived from the optic disc segmentation and data derived from the optic cup segmentation into an adaptive model operative to generate a CDR value, wherein the adaptive model is obtained by an automatic learning algorithm using a database of retinal fundus images.
