基于手背血管进行身份识别的预处理研究

Study on identity authentication pre-processing based on hand vein

分析生物识别技术的发展现状以及研究以手背血管为特征进行身份识别的意义,结合识别系统框图对其中的预处理模块进行了详细阐述,主要包括图像的提取、二值化、去噪、细化等.实验结果表明,处理效果较好.

This paper first analyzes the development status of biometric identification technology, and the meaning of study on identity authentication based on the hand vein, then combines with the identification flow system, and illustrates the preprocess module systematically, including extracting image, binarization, denoising, thinning and so on. The experiment result proves to be good effect .
