Abstract
A computer-implemented method and system for adjustment and matching of stereoscopic images ( ) of the eye fundus ( ). Illumination errors between the images are eliminated, such as by adjusting groups of pixels so that the mean and variance of a group ( ) from the left image ( ) will have the same mean intensity and variance as the corresponding group ( ) from the right image ( ). An epipolar line adjustment is performed, such as by shifting points in the images based on matched points in the images. Image occlusion errors are detected and removed, such as by matching point analysis. Once these adjustment steps have been completed, a matching analysis can be preformed using the corrected images.
