增量式互信息图像匹配

代码说明：

说明：  自己编写 的增量式互信息图像匹配的matlab代码,每一步都有清楚的标注,算是自己在目标追踪学习路上的开始,互信息用于测量模板与图像的匹配程度,增量式可以减少计算的计算量.(The matlab code of incremental mutual information image matching is written by myself. Each step is clearly marked, which is the beginning of target tracking learning. Mutual information is used to measure the matching degree between template and image. Incremental mutual information can reduce the amount of calculation)
