Abstract
We propose a method for automatically enhancing the eyes of all the faces in a digital image by whitening their scleras (i.e., the white part of their eyes). The scleras are identified by combining existing face detection and feature alignment technology with a color-based sclera probability map. We then smooth, brighten, and desaturate the scleras. This reduces the appearance of blood vessels and produces a healthier, more "refreshed" look.
