Palm recognition based on new feature extraction method
掌纹识别的一种新的特征提取方法*

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...
