| 摘 要： | 本文提出了一种改进的H.264Intra帧的错误隐藏算法,该算法引入方向模板对错误块内的边界方向和幅度进行估计,然后利用邻域边界信息内插错误块内的像素。实验结果表明本算法与参考软件中的方法相比,在具有较好隐藏效果的同时又没有增加运算量。

| Abstract: | In this paper,an improved spatial error concealment algorithm for H.264 is proposed,which introduces direction pattern to estimate the edge directions and extent of lost MB,then uses neighborhood edge information to interpolate the error pixels of lost MB. The result of experiment shows that this algorithm not only has better error concealment effect than the reference software but also doesn't cost more computational complexity. |
