摘要

本文提出了一种考虑前一帧分割决策信息的错误隐藏算法，以改进目前广泛使用的从前一帧推断运动向量的算法。结果表明，该方法在客观上和主观上都有较好的效果。此外，我们的方法在HEVC视频中的改进比在AVC视频中的改进更大，因为HEVC中有更大的划分决策空间来考虑帧中更多不同大小的运动物体。

Error concealment algorithm for HEVC coded video using block partition decisions

In this paper, we propose an error concealment algorithm that considers the partition decision information from previous frame, to improve a widely used algorithm that extrapolates the motion vectors from previous frame. The result shows that objectively and subjectively, the proposed method can perform better. Also, the improvement of our method is larger in HEVC video than in AVC video, due to larger partition decision space in HEVC to account for more various sizes of moving objects in a frame.
