Multi-view video coding by using the hierarchical B picture structure utilizes intra-view and inter-view predictions to reduce redundant information. The best coding mode is determined by exhaustively searching over all possible partition modes using rate distortion comparison in motion estimation for each macroblock. However, there is a high computational complexity in exhaustive searching. This...
H.264/AVC the latest international video coding standard achieves higher compression efficiency than previous video coding standards. However, this performance gain comes at the cost of an increased computational complexity. To achieve a high coding efficiency, H.264/AVC employs complex mode decision techniques based on Rate-Distortion Optimization, the computational complexity is very high. This...
To decrease the computational complexity of adaptive inter-layer prediction and improve the encoding efficiency in spatial and temporal scalable video coding, a mode decision algorithm is proposed by exploiting the part of used modes in the co-located reference macroblock(s) for Hierarchical-B pictures of all layers. This scheme generates a reduced dynamic candidate list for the current macroblock...
H.264/AVC encoder complexity is remarkable mainly due to variable block size motion estimation (ME) and exhaustive rate distortion optimization (RDO). This makes real-time video coding very difficult. In this paper, a novel fast mode decision algorithm for P-slices is presented to reduce the computational load. Based on the temporal and spatial correlation between macroblocks, a four paths prediction...
The newly proposed video coding standard H.264/AVC by JVT can achieve much higher efficiency than previous standards. Unfortunately this comes at a cost in greatly increased complexity at the encoder mainly due to motion estimation (ME) and inter /intra prediction block mode decision. In this paper, we propose a fast mode decision algorithm for H.264/AVC based on all-zero blocks predetermination....
