AVS2 Fast Intra Mode Decision Hardware Design

Proceedings of the 2020 4th International Conference on Electronic Information Technology and Computer Engineering, 2020
AVS2 is a kind of advanced video coding standard developed by China, which achieves the same compression efficiency as the international standard HEVC/H.265. In intra coding, there are 33 intra prediction modes, and the optimal intra prediction mode is obtained by calculating Rate Distortion (RD) cost of each mode.

Fast mode decision algorithm for intra prediction in HEVC

Proceedings of the Fifth International Conference on Internet Multimedia Computing and Service, 2013
The High Efficiency Video Coding (HEVC) standard achieves much better efficiency than previous video coding standards. One contributor to this improvement is the large set of intra prediction modes that it supports. While resulting in the better Rate-Distortion (R-D) performance compared to the H.264/AVC equivalent predictor, it suffers from heavier ...

Fast intra mode decision for depth map coding

2013 IEEE International Symposium on Consumer Electronics (ISCE), 2013
Nowadays, JCT-3V joined by ITU-T VCEG and ISO/IEC MPEG is developing new 3D video coding standard, MVC+D and 3D-AVC, based on H.264/AVC. In addition to color image, depth map is also included to be compressed because of adopting DIBR to generate virtual views.

A fast mode decision algorithm for HEVC intra prediction

2016 Visual Communications and Image Processing (VCIP), 2016
The latest video coding standard, High Efficiency Video Coding (HEVC) can achieve up to 50% bit rate saving while maintain the same subjective quality compared to H.264/AVC. However, this great advance is obtained at the expense of significantly increased encoder complexity. In this paper, a two-step algorithm focusing on fast mode decision is proposed

Fast Intra Mode Decision for HEVC

2016
High Efficiency Video Coding (HEVC/H.265), the latest standard in video compression, aims to halve the bitrate while maintaining the same quality or to achieve the same bitrate with an improved quality compared to its predecessor, AVC/H.264. However, the increase in prediction modes in HEVC significantly impacts on the encoder complexity.

Fast mode decision algorithm for intra prediction in HEVC

2011 Visual Communications and Image Processing (VCIP), 2011
As the next generation standard of video coding, the High Efficiency Video Coding (HEVC) is intended to provide significantly better coding efficiency than all existing video coding standards. To improve the coding efficiency of intra frame coding, up to 34 intra prediction modes are defined in HEVC.

Efficient Intra Mode Decision Via Statistical Learning

2007
Intra mode selection and motion estimation for spatial and temporal prediction play important roles for achieving high video compression ratio in the latest video coding standards, such as H.264/AVC. However, both components take most of the computational cost in the video encoding process.

A Fast Intra-mode Decision Scheme for HEVC

2014 5th International Conference on Digital Home, 2014
Compared with H.264/AVC, the newly published High Efficiency Video Coding (HEVC) standard improves the intra prediction by introducing much more prediction modes and novel techniques, which brings great computational burden. Although the rough mode decision (RMD) scheme in HEVC provides a way to speed up the process, it does not consider the similarity

A fast intra mode decision algorithm for AVS

IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010
The AVS video coding standard employs a robust Rate-Distortion Optimization (RDO) technique to improve compression performance. Although RDO technique can achieve better compression efficiency, it also increases tremendous computational complexity. In order to reduce complexity, this paper proposes a fast intra mode decision algorithm for AVS based on ...
