这是数字视频方面的知识，里面的代码是用MATLAB进行编写的，实现的功能是利用多约束的方法进行目标跟踪，是学习数字视频图像不错的一个例子。(This is a digital video knowledge, which the code is written in MATLAB to achieve the functionality is the use of multi-target tracking method constraints, is learning digital video images of a good example.)

It can read file, read electric charge etc

说明：  空间调制SCMA及MPA检测，对这方面的学习很有帮助(SM SCMA and MPA detection)
