低对比度手背静脉图像的增强和分割
Enhancement and Segmentation of Low Contrast Hand Dorsal Vein Image
摘要
Abstract
The human hand dorsal vein recognition technology is a biometric technology. The human hand dorsal has much more veins than the fingers, and can be extracted more features for authentication, so the hand dorsal vein recognition as an authentication approach used in the field of information security has a very important practical significance. Due to the difference of the light intensity and the thickness of hand dorsal, the quality of the hand dorsal image is not very good. The hand dorsal vein images have lower contrast degrees. In order to acquire better contrast hand dorsal vein images, a hand dorsal vein processing method that combines the morphology method and the contrast limited local histogram equalization (CLAHE) is presented. Experiments indicate that the proposed method can strengthen the contrast degrees of the hand dorsal vein and background effectively, and has a significant effect on the segmentation of hand dorsal vein.关键词
