H.264/AVC is the latest international video coding standard developed by ITU-T Video Coding Expert Group and the ISO/IEC Moving Picture Expert Group, which provides gains in compression efficiency of about 40% compared to previous standards (ISO/IEC 14496-10, 2004, Weigand et al., 2003). New and advanced techniques are introduced in this new standard, such as intra prediction for I-frame encodi...

We present and analyse schemes for the improvement of computational complexity in the current HEVC (High Efficiency Video Coding) standard, by a subsampling of the block-matching distortion cost functions used in the encoding process. HEVC improves on prior standards considerably in coding (compression) efficiency, with a large set-back in time complexity for inter and intra prediction processe...
