摘要

本文首先简要介绍几种空域错误掩盖技术

然后提出了多向变长区间的空域内插错误掩盖技术. 该技术是基于错误块邻域的边界特性选择空域内插方向和参考区域

使得掩盖的视频图像既保持了边界信息又减小无关区域的影响. 实验结果表明本文算法有效地提高了错误图像的掩盖效果.

Abstract

In this paper

we briefly introduce several methods for spatial error concealment

and then propose the algorithm of multi-directional and variable-interval interpolation for spatial error concealment.The proposed method chooses both interpolation directions and reference area according to the edge feature of the neighboring blocks.The experimental results show that the quality of the image processed using the proposed error concealment method is significantly improved.
