中文说明：实现典型相关分析，可以广泛的应用于数据预测及数据分析,利用matlab针对图像进行马氏距离计算 ,本程序的性能已经达到较高水平，结合PCA的尺度不变特征变换(SIFT)算法，应用小区域方差对比，程序简单。
English Description：
Typical correlation analysis of implementation, can be widely used in data and data analysis, calculated using the MATLAB Mahalanobis distance for image, this program has reached a higher level of performance, combined with the PCA of the scale-invariant feature transform (SIFT) algorithm of small regional variance comparison program is simple.
