说明：  本程序实现基于差平方和的图像匹配，本程序的优点是在大噪声条件下的匹配成功率很高，缺点是随着匹配区域以及图像的扩大，程序的耗时越来越长
(This procedure square and bad based on the implementation of image matching, the advantages of this procedure are in the noise of the match under the conditions of a very high success rate, with the disadvantage match the expansion of regional as well as images, more and more time-consuming process long)
