Abstract

Method, apparatus, and computer program product are provided. The method includes computing a first difference image for a first eye region based on a difference of red pixel intensity and green pixel intensity of each of a first set of pixels associated with the first eye region. The method further includes determining a first eye color defect region by computing a neighborhood processed first difference image by processing the first difference image, computing a first central point of the neighborhood processed first difference image based on a weighted centroid of red pixels associated with the neighborhood processed first difference image, and thereafter computing the first eye color defect region based on the first central point, and the red pixels associated with the first difference image.
