Fast coding tree unit decision for HEVC intra coding

2013 IEEE International Conference on Consumer Electronics - China, 2013
The Quad-tree structure in HEVC contributes to significant coding efficiency improvement, especially for high resolution videos. However, its recursive representation increases the coding complexity as well. This paper brings forward a fast coding tree unit algorithm to speed up the original intra coding in HEVC.

Edge-aware coding tree unit hierarchical partitioning for quality scalable compression of depth maps

Multimedia Systems, 2021
The scalable extension of the high efficiency video coding standard (SHVC) combines the large compression efficiency and high visual quality of HEVC, with the possibility of encoding different versions of the same video in a single bitstream. However, this comes at the cost of high computational complexity.

Fast Coding Tree Unit depth decision for high efficiency video coding

2014 IEEE International Conference on Image Processing (ICIP), 2014
High Efficiency Video Coding (HEVC) is the latest video coding standard, which adapts quadtree structure based Coding Tree Unit (CTU) to improve the coding efficiency. In HEVC encoding process, the CTU is recursively partitioned into coding units according to the quadtree depth.

A fast Coding Tree Unit depth Prediction for HEVC

2015 8th International Congress on Image and Signal Processing (CISP), 2015
High Efficiency Video Coding (HEVC) standard employs Coding Tree Unit (CTU) quadtree partition technology to improve the compression efficiency significantly, but it also consumes an enormous encoding computational complexity. In this paper, a fast CTU depth prediction algorithm is proposed.

Saliency-based coding tree unit-level rate control for high-efficiency video coding

Journal of Electronic Imaging, 2018
Visual saliency is used to guide the coding tree unit (CTU)-level bit allocation process in high-efficiency video coding (HEVC) to improve the visual quality. At first, a saliency detection algorithm is proposed. With the detected saliency map, the distortion of each CTU is weighted by the corresponding saliency, so that the distortion of the salient ...

Optimal stopping theory based fast coding tree unit decision for high efficiency video coding

2016 Visual Communications and Image Processing (VCIP), 2016
High Efficiency Video Coding (HEVC) is the most recent video coding standard aiming to further reduce the bitrate over 50% as compared to the state-of-the-art H.264/Advanced Video Coding under the same visual quality. In order to achieve this, a number of advanced coding techniques have been adopted in HEVC, including the quadtree structure of Coding ...

Adaptive coding-unit size selection based on hierarchical quad-tree correlations for high-efficiency video coding

Journal of Electronic Imaging, 2015
The latest high-efficiency video coding (HEVC) standard adopts a recursive quad-tree block structure with the coding-unit (CU) size variable depending on video content. It substantially improves the coding efficiency and also dramatically increases complexity.
