Distributed Video Coding (DVC) is a popular topic in the research community and the past years have seen several different implementations. DVC has been proposed as a solution for applications that have limited battery resources and low hardware complexity, thus necessitating a low complexity encoder. An ideal application would be in remote surveillance/monitoring or live video conferencing. However,...
In this paper, an efficient search center definition algorithm is proposed for H.264/AVC. H.264/AVC achieved high coding efficiency by introducing some new coding tools including a new definition of the search center. However, the definition of the search center is not efficient in the case of significant motions. This work proposes some new search center candidates using spatial and temporal correlations...
The seven prediction modes for P-slice provided in the inter-frame coding tool of H.264/AVC enables significant compression gain but at the cost of computational complexity. To address the issue, we propose in this paper a fast mode decision algorithm that is able to reduce the computational complexity of this coding tool by exploiting the coding modes of previously coded neighboring blocks and by...
A fast macroblock mode selection algorithm based on inter-view global disparity is proposed to improve the encoder efficiency of JMVM, with insignificant degradation in picture quality and bit rate increase. The proposed fast mode selection algorithm promotes the encoding speed through partly searching method when encoding most of the frames in multiview video sequence. The macroblock mode of current...
The H.264/AVC standard achieves higher coding efficiency than the previous video coding standards with the rate-distortion optimization (RDO) technique which selects the best coding mode and the reference frame for each macroblock (MB). As a result, the complexity and computational load have been significantly increased. In this paper, a novel fast intra-mode decision algorithm is proposed to reduce...
