Fast PU Intra Mode Decision in Intra HEVC Coding

2019 Data Compression Conference (DCC), 2019
As 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 size decision and mode decision algorithm for HEVC intra coding

2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM), 2019
The 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.

A Fast Intra Mode Decision Method for HEVC

2020 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-Taiwan), 2020
The High Efficiency Video Coding (HEVC) standard can achieve approximately 50% bit-rate reduction that compares with H.264. To enhance intra coding efficiency in HEVC, an increase in the number of intra modes from 9 to 35 is adopted. However, this technique drastically increases computational complexity of intra mode selection.

Fast intra mode decision strategy for HEVC

2013 IEEE China Summit and International Conference on Signal and Information Processing, 2013
This 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

Fast intra prediction mode decision using parallel processing

2005 International Conference on Machine Learning and Cybernetics, 2005
H.264 adapts rate distortion optimization (RDO) technique to get high coding rate and visual quality. Because RDO is too much exhaustive, several attempts have been made to explore fast algorithms. In all algorithms computational speed increased with a performance degradation.

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

An efficient intra-mode decision method for HEVC

Signal, Image and Video Processing, 2016
This paper proposes a new intra-mode decision method for HEVC. The proposed method makes use of the characteristics of some special modes that belong to both rough mode decision mode set and most probable mode set. It also improves the coding efficiency by adaptively applying different algorithms depending on the prediction unit size. Not only the luma

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.

Adaptive Fast Mode Decision for HEVC Intra Coding

2016 International Conference on Digital Image Computing: Techniques and Applications (DICTA), 2016
The latest High Efficiency Video Coding (HEVC) standard offers higher performance than existing video coding standards - up to 50% bit-rate reduction at the equal perceptual quality, but with a significant encoder complexity increase. With regard to intra prediction, a set of 35 intra prediction modes is defined in HEVC to enhance the intra coding ...

Improved fast intra mode decision with reliability refinement

2013 IEEE China Summit and International Conference on Signal and Information Processing, 2013
Fast intra mode decision algorithms in video coding are very useful and necessary for practical real-time encoder implementation. It reduces the computational complexity by eliminating unlikely modes from candidate set. However, most of these algorithms may lead to the noticeable quality degradation, especially for the all intra coding scenario.
