| 摘 要： | 通过分析已有的掌纹识别方法和特征提取所面临的问题，提出了一种新的掌纹识别算法——直接监督保局投影(DSLPP)。该算法在传统的保局投影（LPP）算法中加入类别信息，同时对角化XLX T和XDX T，可以直接达到保局投影算法的最优准则，并且无须在原始高维数据(如原始图像)上先进行任何特征提取或降维处理。在PolyU 掌纹库中进行实验，与Eigenpalm、Fisherpalm和LPP算法相比具有较高的识别速度和识别率；当掌纹库中图像总数为600张，共100人，每人用5张掌纹图像作为训练样本，1张掌纹图像作为

| Abstract: | By analyzing the existing methods of palmprint recognition and the problem of feature extraction,this paper proposed a new palm image feature extraction and recognition method based on direct DSL PP. This algorithm added the class information into the traditional LPP and diagonalized both XLXTand XDXT simultaneously. Achiered the optimize Fishers criterion directly,without any feature extraction or dimensionality reduction steps on high-dimensional data (such as raw images). Tested and evaluated the propose... |
