Despite its remarkable coding efficiency, the computational complexity of the spatial-domain intra prediction scheme of H.264 remains a challenging issue especially for applications of the high profile, as it incorporates the additional intra 8times8 prediction mode. To address this issue, we propose in this paper a fast selective intra mode decision algorithm that exploits a newly discovered property...
Belief propagation is a popular global optimization technique for many computer vision problems. However, it requires extensive computation due to the iterative message passing operations. In this paper, we present a new process element (PE) for efficient message construction. The efficiency is gained by exploiting the unique characteristics of the generalized Potts model (truncated linear mode) of...
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...
