对视频进行运动检测，基于相邻两帧帧间差分。 在相邻两帧（也可以为多帧）间计算逐象素的灰度差，并通过设置阈值来确定对应运动前景的象素，进而得到运动前景区域。-On a video motion detection, based on the two adjacent interframe difference. The gray-scale difference between the two adjacent frames (may be a multi-frame) calculating

基于OpenCV2.4.4+Visual Studio2008下的多目标跟踪代码。基于帧间差分法判断视频的背景和前景。-OpenCV2.4.4+ Visual Studio2008-based multi-target tracking code. Based on inter-frame difference method to determine the background and foreground of the video.

背景平均方法来从视频文件提取的目标读，多帧叠加平均为背景，前景对象减法是，各种改变后-Background averaging method to extract goals video files to read, multi-frame superimposed averaged as a background, the foreground object subtraction was, after various changes
