离散小波变换，然后主成分分析进行数据降维，用于模式识别，如人脸识别，掌纹，-Discrete wavelet transform, and then principal component analysis for data dimensionality reduction for pattern recognition, such as face recognition, palm prints,

基于gabor变化与pca结合的掌纹识别-palmprint identification

gabor滤波的纹理提取，对于掌纹识别很有用-Gabor filter texture extraction, useful for palmprint recognition!
