This paper presents a novel error concealment method for stereoscopic video which makes use of the illumination changes between different views. Our goal is to improve the quality of the reconstructed macroblocks with disparity compensation prediction in a stereoscopic video coding system by compensating illumination difference between two views. Experimental results show that the proposed method...
In this paper, we present an adaptive stereo video object segmentation algorithm based on depth and spatio-temporal information. First, the object is extracted from the left channel with a new algorithm, which consists of three steps: depth segmentation, adaptive change detection based on twice frame-difference, and edge modification. Then, an inverse matching operation is proposed for object extraction...
Segmentation of semantic video object planes (VOPpsilas) from video sequence is a key to the standard MPEG-4 with content-based video coding. In our paper, we propose an automatic segmentation algorithm under static background. The algorithm can extract accurate video objects from slow moving video sequences. The initial two coarse masks are first obtained based on frame difference and motion detection,...
A step-variable shot detection algorithm of soccer video based on DC image is presented in this paper. The proposed method uses the DC image as original data and the grass ratio as feature parameter in soccer field. This algorithm only needs partly decompression from the encode bit-stream and doesnpsilat need all the histogram comparison between adjacent frames, so it can reduce the computational...
In this paper, an algorithm to segment object from stereo video is presented. The algorithm combines the strong points of disparity map with frame difference. First, segment disparity maps to get the object segmentation template in different disparity lays. Then make frame difference extraction in the template regions to modify the object edge. After that the precise motion object has been gotten...
