| 摘 要： | 提出了一种新的基于时空信息的视频分割算法．即先将原始图像标记成不同的区域，然后以帧间差分得到的对象运动信息作为评判准则，将这些区域分别归类于前景对象和背景．达到对象分割的目的。特别是在区域标记的过程中，采用了一种新的基于分水岭的区域标识技术。通过对标准图像序列的实验结果可以看到，利用该算法能够较精确地分割出视频对象。

| Abstract: | In this paper, we propose a new segmentation method to separate the moving objects from the background in a generic video sequence. It is to support the content-based functionalities focused by the MPEG-4. The proposed algorithm discriminates background from foreground by means of spatio-temporal information. First, the original image is labeled into different regions. Then, some regions are merged to form video object according to the inter-frame difference information as judgement criterion, and others are discarded. Experimental results obtained on some typical MPEG-4 sequences are shown in order to illustrate the segmentation algorithm performance. |
