We propose an algorithm for facial expression recognition which can classify the given image into one of the seven basic facial expression categories (happiness, sadness, fear, surprise, anger, disgust and neutral). PCA is used for dimensionality red

SIFT算法的相关实现 自己用matlab写的sift特征点检测与匹配程序，运行能通过-SIFT algorithm related to realize their written with matlab sift feature point detection and matching program, run through

Matlab 写的sift查找特征点和特征匹配的算法代码。 输入两幅图像，检测特征点并匹配，输出匹配结果-Matlab write sift Find feature points and feature matching algorithm code. Enter the two images, the feature point detection and matching, output matching results
