FCM-Based Fast Texture CU Size Decision Algorithm for 3D-HEVC Inter-Coding

2020 IEEE/ACS 17th International Conference on Computer Systems and Applications (AICCSA), 2020
3D-HEVC is an extension of High Efficiency Video Coding (HEVC) standard. The Coding Unit (CU) sizes in 3D-HEVC, namely, depth levels are splitting on different block sizes from 64×64 to 8×8 in texture video and depth map associated, which brings a great computational complexity.

Fast CU Size Decision Algorithm Based on Minimum Mean Squared Error Estimators

2014 5th International Conference on Digital Home, 2014
A fast CU size decision algorithm is proposed for High Efficiency Video Coding (HEVC) intra prediction in this paper. Prediction unit (PU) is decided by analyzing the threshold of judgment, the complexity of the algorithm is increased if the threshold is too big, and the quality of the image is seriously damaged if the threshold is too small.

Fast CU size decision algorithm using machine learning for HEVC intra coding

Signal Processing: Image Communication, 2018
Abstract High Efficiency Video Coding (HEVC) is a state-of-the-art video compression standard which improves coding efficiency significantly compared with the previous coding standard, H.264/AVC. In the HEVC standard, novel technologies consuming massive computational power are adopted, such as quad-tree-based coding unit (CU) partitioning.

Self-learning residual model for fast intra CU size decision in 3D-HEVC

Signal Processing: Image Communication, 2020
Abstract As an extension of the High Efficiency Video Coding (HEVC) standard, 3D-HEVC requires to encode multiple texture views and depth maps, which inherits the same quad-tree coding structure as HEVC. Due to the distinct properties of texture views and depth maps, existing fast intra prediction approaches were presented for the coding of texture ...

Fast intra mode decision and fast CU size decision for depth video coding in 3D-HEVC

Signal Processing: Image Communication, 2019
Abstract 3D-HEVC is the new coding standard for both texture and associated depth video. In addition to several new coding tools that are designed for texture video with improved coding efficiency, some tools are specified for depth video, such as depth modeling modes (DMMs), segment-wise DC (SDC) mode and depth intra skip mode.

A Fast HEVC Inter CU Size Decision Algorithm Based on Multi-Class Learning

2018 10th International Conference on Intelligent Human-Machine Systems and Cybernetics (IHMSC), 2018
HEVC achieves much higher coding efficiency compared with previous coding standards at cost of significant computation complexity. This paper proposes an efficient machine-learning based inter CU size decision algorithm for HEVC. The proposed algorithm uses a wrapper method based on F-score to select features in several factors that may be related to ...
