中文说明: PCA是人脸识别的一大主要方法,本代码致力于得到expression-invariant faces的人脸识别PCA方法。 主要采用小波变换提取人脸低频部分,并赋予不同特征脸不同权重的方法,得到改进后的PCA方法,并与原PCA方法进行对比,观察其在人脸识别上的准确率的提升。
English Description:
PCA is one of the main methods of face recognition, the code is committed to get the faces PCA face recognition expression-invariant method.Mainly uses wavelet transform extract the low-frequency part of the face, and give different feature face different weight method, the improved PCA method, and compared with the original PCA method, observe the accuracy rate in face recognition.
