Block-based coding in H.264/AVC creates discontinuities at block boundaries. The blocking artifact is regarded as the most visible artifact in block-based video coding. In H.264, a deblocking filter is used to reduce such a blocking artifact. However, it requires a significant amount of complexity and it occupies one-third of the computational complexity of the decoder. In this paper, we propose a...
This paper proposes a novel multi-frame error concealment algorithm for the whole-frame losses in video transmission based on H.264/AVC. In order to minimize the error propagation, the proposed algorithm estimates the distortion of both the lost frame and its succeeding frame, and determines the modes for recovering the motion vectors of the lost frame. In addition, based on the analysis of the computational...
