摘要
立体视频对象分割是新一代视频编码、视频检索、互联网多媒体交互等新兴领域的关键技术.该文提出了一种融合多种信息的立体视频对象分割算法,首先采用基于边缘特征约束的视差估计方法,获得了可靠的视差场,再利用视差信息对视频对象进行了初始分割,在此基础上结合帧间变化检测的信息对视差分割结果进行修正.实验结果表明,本算法对有重叠的多对象具有良好的分割效果,得到了较精确的视频对象.
Stereo video object segmentation is a key technology in the new generation video coding, video browsing, and Internet multimedia interacting, etc. In this paper, a stereo video object segmentation algorithm that combines various sources of information is proposed. Estimation of disparity based on edge character restriction is ilrst adopted to obtain reliable disparity scene. segmentation. Change detection information is then integrated Experimental results show effectiveness of the algorithm in the The disparity information is used to initialize to modify boundaries of disparity segmentation. case of multiple object overlapping.
