A novel method based on independent comment analysis(ICA) and back propagation neural network(BPNN) was proposed to solve palmprint recognition.First,a new method was used to detect corner points as the invariant feature points in palm images.Then the palm images were aligned by the points,and the region of interest(ROI) of the images was gotten.In the next place,palmprint features were extracted from the ROI by a fast fixed-point algorithm for ICA(FastICA).By means of this method,the original palmprint ROI...

掌纹识别是利用人的掌部纹理作为生物特征进行身份的自动确认,是生物认证领域的一种新的识别技术.掌纹信息主要集中在掌心的一个很小的区域内,这个区域通常被称为感兴趣区域(ROI,Region of Interest).因此,如何有效地提取ROI区域关系到识别精度.文献[1-2]采用基于不变特征点的?
