自适应目标跟踪程序，包括目标检测和块匹配法实现的目标跟踪-Adaptive target tracking procedures, including target detection and block matching method to achieve the target tracking

基于帧差法与图像块匹配方法的运动目标检测与跟踪，可以实际操作，性能还不错的(The moving target detection and tracking based on the frame difference method and the image block matching method can be actually operated, and the performance is good.)
