摘要:
人体手背静脉识别技术是生物特征识别技术的一种。人的手背拥有比手指更为丰富的静脉血管,可以提取更多的并且适于身份认证的特征,所以把手背静脉识别作为一种身份认证方式,应用于信息安全等领域具有非常重要的现实意义。由于光照强度、下背厚度的不同,所采集到的手背静脉图像的质量不是很好,对比度比较低。为了得到有较好对比度的手背静脉图像,提出了一种綦于形态学处理与对比度受限的局部直方图均衡(CLAHE)相结合的手背静脉图像处理的方法。,实验表明,这种方法能有效地增强手背静脉和背景的对比度,使得静脉分割取得了很好的效果
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
