基于拟合平面插值的时域错误隐藏算法研究
Temporal Error Concealment Algorithm Based on Fitting Plane
摘要
Abstract
In a wireless transmission,H.264/AVC compressed video stream can result in lower quality of image reconstruction by the mismatch of motion vectors,a temporal error concealment algorithm based on the fitting plane interpolation algorithm is proposed.This algorithm reconstructs the motion vector of the damaged macro-block by the fitting plane algorithm,and uses the outer boundary matching algorithm to select the best motion vector to reconstruct the damaged images.This algorithm not only avoids the block effects that caused by the original algorithm,but also in different probability of RTP packet losing,the peak signal to noise ratio of the algorithm has improved 0.2 dB~0.8 dB compared to the adaptive boundary matching algorithm.关键词
