实现了基于码书的运动检测，并有与其他的检测算法做对比，例如MOG，Bayes，三帧差分等。,Codebook based on the realization of the motion detection, as well as with other contrast detection algorithm, such as MOG, Bayes, differential, etc. 3.

在广泛研究前人工作的基础上，本文对运动人物的检测、跟踪与识别进行了综述。为 使分类清楚明了，本文将人物运动分析分为两大类：人体运动分析，人脸分析。人体运动分 析包括人的较大幅度的肢体运动，如手势识别、步态分析、整个人体的运动分析；人脸分析 包括人脸检测与识别、表情分析。在详细介绍了国内外研究现状后，提出了存在的问题及研 究前景。-Extensively studied in previous work on the basis of the figures in this art

Motion detection results If you double-click the Switch block so that the signal is connected to the SAD side, the Video Viewer block displays the SAD values, which represent the absolute value of the difference between the current and pr
