数字视频监控系统中实时运动检测系统的研究

在数字视频监控系统中，从视频流里捕获出序列图像并进行实时运动检测是一项重要的功能。采用两个进程分别实现视频图像的捕获和运动检测，命名管道作为两个进程之间数据通信的桥梁。提出了一种基于帧差交集快速视频分割法、阈值面积算法结合数学形态学运算提取运动目标区域的数字图像处理算法，然后再进行运动目标的跟踪定位，实现实时运动检测。

Research of Real-time Motion Detection System in Digital Video Supervisory System

In digital video supervisory system, it's an important function that captures image sequence from video-stream and detects the moving objects in real time based on image sequence. This paper creates two processes to capture the image sequence and implement real-time motion detection. The named pipe method is used for two processes to communicate. A novel digital image processing algorithm is presented, which is fast video segmentation method based on intersection of frame differences and threshold area algorithm combined with morphological operation to extract moving region. After the moving region was obtained, the motion object can be tracked and the real-time motion detection algorithm was implemented.
