A method was proposed to reconstruct, segment and measure the optic cup and disk in a color image of optic nerve heads for the computer aided diagnostics of glaucoma diseases. First, a hierarchical Mumford-Shah model was employed to reconstruct the optic cup and disk. Then, the optic cup and disk characteristic rectangles and edge points were extracted based on the color reconstruct image of an optic nerve head by incorporating the prior knowledge of the optic cup and disk shapes. Finally, smoothing spline curve fitting was resorted to reconstruct the edges of the optic cup and disk obscured by blood vessels, and the measurements of the optic cup and disk were estimated. Tests were conducted on the color optic nerve head images of different glaucoma patients. Results showed that the proposed method was able to handle the images which were with poor quality, very low contrast, obscure due to blood vessels, and distinct inter-differences of individuals, and thus to effectively segment, reconstruct and measure the optic cup and disk in a color image of optic nerve heads.
