轮廓基的视频对象平面提取方法

Method for extracting video object plane based on contour

提出一种基于轮廓信息的视频对象平面（VOP）半自动提取方法，运用边缘点拾取、轮廓闭合、腐蚀和轮廓运动补偿等多项技术，充分考虑到轮廓的规则形变和无规则形变。实验结果表明，此方法具有对象边缘精确，适应性强的特点，提取的VOP令人满意。

In this paper， a contour-based VOP generation scheme is presented which utilizes combination of methods such as boundary pixels pick-up， contour closing， erosion and contour motion compensation to deal with the regular and irregular warp of the contour． Experimental results have shown the satisfactory results which takes the features of precise boundary and robustness．
