Moving object detection by fr a me difference method是当前视频图像领域进行动目标捕捉的最简单有效的方法，核心思想是从视频中提取每一帧，并与下一帧做相关检测，通过相关系数提取运动的目标。-Moving target detection and fr a me difference method is the current video image field is moving the most simple and effective method to capture the target, the core idea is to extract each fr a me　the video, and correlation detection and the next fr a me, extract the moving target by correlation coefficient.
