摘　　要：本文对近年来提出的局部保留映射(LPP)算法和判别局部保留映射(DLPP)算法思想进行了详细介绍,设计并完成了基于LPP和DLPP算法在掌纹识别中识别结果的对比实验。实验结果对基于这两种算法的掌纹识别方法给予数据支持,而且说明DLLP算法要优于LPP算法。In this paper, the algorithms of Locality Preserving Project （LPP） and Discriminant Locality Preserving Project （DLPP） are explicitly introduced. Several contrast experiments based on LPP and DLPP are designed and performed to evaluate their effectiveness in palmprint recognition. The experimental data supports the method of using these two algorithms in palmprint recognition, and also shows DLPP is superior to LPP in recognition performance.
