Fast Intra size decision and mode decision algorithm for HEVC intra coding
2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM), 2019The latest High Efficiency Video Coding (HEVC) standard could achieve much higher coding efficiency than the current mainstream video coding standards (H.264/AVC). Compared with H.264/AVC, H.265 saves 50% cost than H.264/AVC at the same quality. But compression ratio gets improved with at least 2-4 times increase in computational complexity.

Fast PU Intra Mode Decision in Intra HEVC Coding
2019 Data Compression Conference (DCC), 2019As an upgrade for H.264/AVC, high efficiency video coding (HEVC) achieves 50% bitrate reduction under the equivalent visual quality. However, high computational complexity increases dramatically for adopting up to 35 intra prediction modes. To deal with this issue, we explore spatial-temporal correlation between PUs to narrow rough mode decision (RMD ...

Fast intra mode decision strategy for HEVC
2013 IEEE China Summit and International Conference on Signal and Information Processing, 2013This paper proposes a fast intra prediction mode decision strategy for HEVC (High Efficiency Video Coding), which aiming at reducing computation time and keeping the coding performance at the same time. Using a notation of a circle, we arrange the candidate modes into different groups. The order of processing MPM(most probable modes) and RMD(rough mode

An adaptive fast intra mode decision in HEVC
2012 19th IEEE International Conference on Image Processing, 2012Compared with H.264/AVC, the emerging video coding standard, High Efficiency Video Coding (HEVC), introduces a lots of intra prediction modes in intra coding, which brings a real challenge in practice. Although the Rough Mode Decision (RMD) scheme in HEVC provides a fast mode decision, it is a fixed strategy for different blocks with the same size and ...

Fast intra mode decision for HEVC intra coding
The 18th IEEE International Symposium on Consumer Electronics (ISCE 2014), 2014This paper proposes an adaptive intra mode selection algorithm with rough mode decision (RMD) stage and an early termination for rate-distortion optimization (RDO) stage for fast intra coding of High Efficiency Video Coding (HEVC). The proposed adaptive mode selection for fast intra coding employs the prediction modes from the upper layer of coding ...

A fast mode decision algorithm for HEVC intra prediction
2016 Visual Communications and Image Processing (VCIP), 2016The 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

AVS2 Fast Intra Mode Decision Hardware Design
Proceedings of the 2020 4th International Conference on Electronic Information Technology and Computer Engineering, 2020AVS2 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, 2013The 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 ...
