通过sift算法进行图像配准，配准效果好，精度高(Image registration algorithms sift through the good registration results, high precision)

用Gabor滤波器和稀疏分类对表情进行识别(By Gabor filters and sparse facial expression classification identify)

按照最邻近原则把待分类样本点分到各个簇。然后按平均法重新计算各个簇的质心，从而确定新的簇心。一直迭代，直到簇心的移动距离小于某个给定的值。(According to the nearest neighbor principle, the sample points to be classified are divided into clusters. Then the centroid of each cluster is recalculated according to the average method to determine the new cluster center. Iterate until the moving distance of the cluster center is less than a given value)
