The latest video coding standard, H.264/AVC, could achieve higher encoding performance compared with previous versions since it employs many tools to increase the coding accuracy, particularly the rate-distortion optimization technique for mode decision. However, enormous computational complexity is produced because all possible combinations of modes are calculated in order to find the optimal Rate-Distortion...
In order to apply high quality video communi-cation in the mobile device with limited power and comm-unication bandwidth, especially in wireless communication, an efficient solution for video communication should be proposed. So, the latest video coding standard, H.264/AVC, is used for Video Codec in mobile terminals. However, the H.264/AVC standard is much more complex than previous video coding...
In this paper, we proposed a fast intra mode decision algorithm based on spatial-domain energy for H.264/AVC. First of all, the relevance between macroblock (MB) and its 4x4 sub-blocks is employed in our algorithm to determine the Intra prediction block size. And then, in order to further reduce the computational complexity of Intra mode decision radically, mode candidate reduction algorithm is released...
