Saliency-based coding tree unit-level rate control for high-efficiency video coding
Journal of Electronic Imaging, 2018Visual 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), 2016High 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 ...

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.

HEVC coding-unit decision algorithm using tree-block classification and statistical data analysis
Multimedia Tools and Applications, 2016We propose a fast coding unit (CU) depth decision algorithm in the High Efficiency Video Coding (HEVC) procedure based on statistical analysis. First, we derive a set of optimized weights of surrounding CU decisions to predict the current CU decision for 3 different Largest Coding Unit (LCU) classes.

Analysis of Parameters of Trees Corresponding to Huffman Codes and Sums of Unit Fractions
2013 Proceedings of the Tenth Workshop on Analytic Algorithmics and Combinatorics (ANALCO), 2013For fixed t ≥ 2, we consider the class of representations of 1 as sum of unit fractions whose denominators are powers of t or equivalently the class of canonical compact t-ary Huffman codes or equivalently rooted t-ary plane "canonical" trees. We study the probabilistic behaviour of the height (limit distribution is shown to be normal), the number ...

Speeding Up the Decisions of Quad-Tree Structures and Coding Modes for HEVC Coding Units
2013High Efficiency Video Coding (HEVC) is being developed by the joint development of ISO/IEC MPEG and ITU-T Video Coding Experts Group (VCEG) and is expected to be a popular next-generation video codec in the future. HEVC can provide higher compression ratio compared to H.264/AVC standard; however, the coding complexity is dramatically increased as well.
