A jointed space-time video error detection algorithm based on the prior restriction
基于先验约束的空时联合视频错误检测算法

The video error detection is the basis of error concealment, which is studied in a typical application scene in this paper. At first, the error detection algorithm based on spatial feature is improved to adaptively adjust the decision threshold. Then, the feature of video temporal correlation is introduced, and a novel joint space-time video error detection algorithm based on prior restrictions with better applicability is proposed. Finally, the algorithm is simulated in 3G video communication environment, the results indicate that the proposed algorithm has a higher accuracy and provided a reliable basis for error concealment.
