On lossless intra coding in HEVC with 3-tap filters

This paper presents a pixel-by-pixel spatial prediction method for lossless intra coding within High Efficiency Video Coding (HEVC). A well-known previous pixel-by-pixel spatial prediction method uses only two neighboring pixels for prediction, based on the angular projection idea borrowed from block-based intra prediction in lossy coding. This paper explores a method which uses three neighbori...

Fast Intra Coding Based on Reference Samples Similarity in HEVC

A Fast Block Size Decision For Intra Coding in HEVC Standard

Intra coding in High efficiency video coding (HEVC) can significantly improve the compression efficiency using 35 intra-prediction modes for 2N×2N (N is an integer number ranging from six to two) luma blocks. To find the luma block with the minimum rate-distortion, it must perform 11932 different rate-distortion cost calculations. Although this approach improves coding efficiency compared to th...

Differential Pixel Value Coding for HEVC Lossless Compression

High efficiency video coding (HEVC) [1] is a new video coding standard developed by Joint Collaborative Team on Video Coding (JCT-VC) of ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG). Currently, most of coding techniques are established and HEVC version 1 will be released in January 2013 [2]. We ex‐ pect that HEVC is widely used in various applications ...
