| 摘 要： | 针对高速密集视频监控序列建立了一种新的简单的背景重构方法。该方法首先基于帧差序列的时空分布特性,利用高阶统计量理论,获取视频序列公共背景区域;然后根据同一背景帧差图像分布特性相似性,去除运动对于背景的干扰,形成路面背景序列值,从而获得路面背景图像;最后利用计分牌监测的自适应背景更新方法进行背景更新。实验结果表明该方法效果理想,为高速路视频背景重建和运动目标检测提供了新的方法。

| Abstract: | A new and simple technique is proposed to reconstruct the background of high speed dense surveillance sequences.First,the public background of video sequences is extracted by using the space distribution property of a frame difference sequence and the high-order statistics theory.Then,a sequence of road background is formed by removing the background interference caused by motion according to the distribution similarity of a background frame difference image,thus getting a road background image.Finally,the background image is refreshed via an adaptive method of the scoreboard.Results demonstrate the apparent effectiveness of the scheme and it is a new method for reconstructing background and detecting motion target in high speed video. |
