Detecting and correcting red-eye in a digital-image

摘要

Systems and methods of detecting and correcting red-eye in a digital image (12) are described. In one aspect, measures of pixel redness in the digital image (12) are computed. A preliminary set of candidate red-eye pixel areas (50) is identified based on the computed pixel redness measures. Each candidate red-eye pixel area (50) having a computed redness contrast relative to at least one respective neighboring pixel area (51) less than a prescribed redness contrast threshold is filtered from the preliminary set. In addition, each candidate red-eye pixel area (50) located in an area (58) of the digital image having a computed grayscale contrast relative to at least one respective neighboring pixel area (0-7) less than a prescribed grayscale contrast threshold is filtered from the preliminary set.
