摘要
用生物识别中常用的基于特征点的方法、选用点模式匹配来研究静脉识别,将预先从静脉图像中提取的特征点集与输入的待匹配的静脉图像中提取的特征点集进行匹配。
Biometric technology use human being＇ s physical character and behavior character to recognize person＇ s identity automatically by the method of image processing and pattem recognition. Vein Recognition is a new technology of Biometric Recognition, which has many advantages such as high recognition ratio, difficulty to forge, not to be influenced by environment and only can be recognized on vivid. It has become a method to be accepted easily. We select the point pattern matching to study the vein recognition which, based on the characteristic point method, is commonly used by the biological recognition, and match pre - venous images extracted from the input feature sets with the waiting vein image point set of features.
