针对视频监控系统的运动目标检测部分,介绍了以OpenCV为平台,以背景减法与帧差法为基础的检测方法。它以背景减法建立和更新背景模型,利用感兴趣区域的设置提高实时性,引入修正的大津法自适应阈值改善二值化效果,并以帧差法为补充降低虚报率及光照变化的影响。实验表明,该方法可以快速有效地对运动目标实施报警。-OpenCV-based moving object detection method and application of some of the articles I read, I feel

利用前n帧的均值背景作为背景，然后消减法检测运动目标-Mean background subtraction method to detect moving targets

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
