> 中文摘要: 视频目标分割与立体匹配是目标基立体视频编码中的核心技术.首先在单通道视频目标分割的基础上提出一种轮廓跟踪匹配算法,以提取立体视频目标对,然后提出一种基于目标的视差估计算法.它以具有特征信息的像素为匹配基元,结合视差匹配约束进行视差估计,克服了传统块匹配算法视差场不连续、视差精度差的缺点,可以获得较为精确和平滑的视差场.
Abstract:Video object segmentation and stereo correspondence is a key technology in object-based stereo video coding. In this paper, based on an algorithm for extracting video object in one view-channel, a new contour tracking and correspondence algorithm is first proposed for extracting stereo video object pairs. Then, a disparity estimation algorithm based on video objects is proposed. It takes a characteristic pixel as a correspondence primitive and the disparity estimation is implemented with disparity constraints. The disadvantages of discontinuous and imprecise disparities with the traditional block-based algorithms can be improved and a precise and smooth disparity field can be finally acquired.
