Fast and effective CU size decision based on spatial and temporal homogeneity detection
Multimedia Tools and Applications, 2017High-Efficiency Video Coding (HEVC) is the latest video coding standard of the Joint Collaborative Team on Video Coding (JCT-VC). HEVC noticeably improves compression performance when compared with previous standards such as H264, and represents a major step forward in video compression technology.

Texture-based fast CU size decision algorithm for HEVC intra coding
2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2016This paper proposes the texture-based coding unit (CU) size decision (TBCUD) algorithm that includes texture-based block partitioning. While the existing algorithm calculates every CU size, the proposed algorithm only considers the determined CU sizes that are decided by the texture of the image.

Fast intra mode decision and fast CU size decision for depth video coding in 3D-HEVC
Signal Processing: Image Communication, 2019Abstract 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.

Self-learning residual model for fast intra CU size decision in 3D-HEVC
Signal Processing: Image Communication, 2020Abstract 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 ...

Early termination algorithm for CU size decision in HEVC intra coding
2015 9th Iranian Conference on Machine Vision and Image Processing (MVIP), 2015Intra coding in the High Efficiency Video Coding (HEVC) standard can significantly improve the compression efficiency but increasing the number of intra prediction modes and also higher number of Coding Unit (CU) sizes in the HEVC standard imposes much higher computational load compared with intra prediction in H.264/AVC, which substantially is ...

A fast CU size decision algorithm based on adaptive depth selection for HEVC encoder
2014 International Conference on Audio, Language and Image Processing, 2014HEVC adopt a flexible coding unit partition technology to exploit more coding efficiency compare to previous standard H.264/AVC. In HEVC test model (HM), the encoder tries all possible depth levels to find out partition structure with least rate distortion cost for each coding tree block.
