METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR COMPENSATING EYE COLOR DEFECTS

摘要

A red-eye detection and correction method comprises computing a first difference image based on a difference between red pixel intensity and green pixel intensity of a set of pixels (702). The set of pixels are associated with a first eye region of an image. The method further comprises processing the first difference image for computing at least one gradient and at least one projection associated with the at least one gradient (704). Furthermore, the method comprises determining at least one central point based on the at least one projection (706); and thereafter computing the first eye color defect region based on the at least one central point and a plurality of red pixels of the set of pixels (708). The method also comprises mapping an eye color defect location information computed from a low resolution image to be applicable on the original high resolution image, thereby avoiding recomputation.
