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小波变换的掌纹纹理特征描述，采用MFC界面 最终对掌纹进行了描述 -Gabor wavelet transform based texture features describe the palm, using the MFC interface are described in the final of the palm
