Abstract

Abstract: The smoothness of restored video is poor to the complex-texture block for the H.264 standard error concealment algorithm. Aiming at the H.264 questions, the project of adaptive error concealment based on multi-texture direction was proposed. Two thresholding methods were used to set the thresholding of Sobel edge detection algorithm, and the proposed Sobel algorithm was judged to detection the edges of adjacent. Cost function of the boundary pixel difference was combined with to determine the interpolation direction for each pixel of error block, and then, the error block was recovered by the interpolation direction of each pixel. JM8.6 simulation experiments show that the proposed method outperforms the standard algorithm based on subjective and objective measures.
