可以提取一幅图中想要的目标，matlab小波分析程序，有循环检测，周期性检测。- Target can be extracted in a picture you want, matlab wavelet analysis program, There are cycle detection, periodic testing.

该程序是通过摄像头实时检测红色目标，并且标记，计算出质心坐标，请在运行之前确保matlab安装了相应的摄像头驱动-The program is through the camera in real-time detection of the red target, and Mark, the calculated centroid coordinates, make sure before running matlab installed the appropriate camera drive
