camshift算法的实现，利用opencv还进行视屏跟踪，要跟踪的物体是先用鼠标确定，代码已经运行-The realization of the camshift algorithm, using opencv also tracking the screen, to follow the object is to use the mouse determined, the code is running

这是一个用于自动跟踪目标物体的代码，一开始需要用鼠标圈定目标-It is a tool for automatic tracking of the target object code, a need to start with the mouse delineation of target
