图像配准定义为：对从不同传感器、不同时相、不同角度所获得的两幅或多幅图像进行最佳匹配的处理过程.图像配准需要分析各分量图像上的几何畸变，然后采用一种几何变换将图像归化到统一的坐标系统中。在配准过程中，通常取其中的一幅图像作为配准的标准，称之为参考图像；另一幅图像作为配准图像(Image registration algorithm)

此为北京航空航天大学数值分析教材当中的2-5章所涉及问题的MATLAB源程序，程序附有详细的解释，值得学习。(This is the Beijing University of Aeronautics numerical analysis of materials in which the issues involved in Chapter 2-5 of the MATLAB source code, the program with a detailed explanation, it is worth learning.)

This tutorial is designed to give the reader an understanding of Principal Components Analysis (PCA). PCA is a useful statistical technique that has found application in fields such as face recognition and image compression, and is a common technique for finding patterns in data of high dimension. Before getting to a description of PCA, this tutorial first introduces mathematical concepts that will be used in PCA. It covers standard deviation, covariance, eigenvectors and eigenvalues. This background knowledge is meant to make the PCA section very straightforward, but can be skipped if the concepts are already familiar.
