| 摘 要： | 视频对象分割是MPEG（Moving Picture Experts Group）-4视频编码的关键技术．针对常用方法的不足，提出了1种新的视频对象分割算法．形态学滤波后利用分水岭算法实现空域分割，时域分割采用二次帧差求交集的方法获取运动区域，然后时空结合．仿真结果表明该算法简单、快速、准确。

| Abstract: | Video object segmentation is a key technology in MPEG-4 video coding. A new method is proposed, in which, a spacial segmentation is made by the watershed method after morphological filtering, and the moving regions are obtained by the intersection of three twice-frame-diffemnce images. Then, the temporal information with spacial inforrnation is intcgrated. The proposed method proves to be simple, fast and accurate. |

| Keywords: | morphological filter watershed moving regions twice-frame-difference |
