| 摘 要： | 要实现对视频中人体动作的捕捉和分析首先要提取出人体的运动肢体,当视频中背景和人体姿态比较复杂时,帧差法、光流法等传统的运动目标提取方法并不能准确检测出人体运动肢体的轮廓.在帧差法基础上,提出了动态区域边缘点保留法来获取运动区域的边缘点集,并根据人体先验知识总结出一种边缘点整合的算法,用于对运动区域的边缘点集进一步处理,得到了人体运动肢体较为完整的轮廓.实验证明,该方法可以较好地解决背景干扰和人体及服饰的非刚性问题,比较准确地检测出人体运动肢体的轮廓.

| Abstract: | To capture and analyze the pose of human from video we must detect the moving body first.When the background and human posture of the video are complex,the traditional methods of moving object detection such as frame differential method and optical flow algorithm can not detect the contour of moving body accurately.Based on frame differential method,we propose the method of saving the edge pixels in the dynamic region to obtain the edge points of movement.According to the prior knowledge of human body,anoth... |
