Sclera Segmentation and Sclera Vessel Enhancement

Abstract

The construction of blood vessels in the sclera- the white portion of the humanoid eye, is distinctive for each singular, henceforth it is finest suitable for humanoid identification. In biometric authentication sclera pattern based human verification is gaining more importance. The sclera pattern of each human is unique, so analysis sclera pattern for individual gave an effective human identification. We have suggested basic technique for sclera segmentation constructed on Otsu segmentation, a novel scheme for sclera pattern improvement built on Contrast Limited Adaptive Histogram Equalization.
