| 摘 要： | 视频监控面对的场景具有静态的成分和缓变的成分.为了从视频流中稳定地抽取较精确的背景,提出了一种基于场景区分的背景抽取算法.首先通过混合高斯模型对视频序列中稳定的成分进行建模,然后采用Kalman滤波模型对视频序列中变化的成分进行建模,最后采用场景的区分算法将2种模型结果进行处理从而得到背景.实验结果表明:该方法能从视频...

| Abstract: | The scene monitored by intelligent video is stable most of the time and slow changing temporarily.In order to stably and precisely extract the background from the video stream,a background extract algorithm based on the scene distinction has been presented.The mixture of Gaussians and Kalman filter are employed to process and model the stationary parts and slow changing parts separately,and then the scene discrimination algorithm is used to extract the background by processing the result of those two models... |
