Redeye is an annoying defect in photographs caused by red light reflected from blood vessels on the retina when a flashgun is used.As the flashgun is close to the lens in a small sized digital camera

the problem becomes even worse.This paper studies detection and removal of red-eyes based on color space analysis

and proposes an automatic red-eye removal technique.Taking into account the prior knowledge of human face

and through experiments on a number of images

an existing approach to face detection is modified.Parameters in an empirical criterion for face detection are determined

resulting in satisfactory segmentation of the skin area.This is used as a basis for further location of eyes and correction of red eyes.Experimental results confirm the effectiveness of the proposed method.
