Perceptual CU Size Decision and Fast Prediction Mode Decision Algorithm for HEVC Intra Coding

2016 IEEE International Symposium on Multimedia (ISM), 2016
Intra coding has been significantly improved in HEVC over H.264/AVC with quad-tree based coding unit (CU) structure from size 64×64 to 8×8 and more prediction modes. However, these techniques cause a dramatic increase in computational complexity. In this paper, a novel intra coding algorithm is proposed consists of perceptual CU size decision algorithm

Texture-based fast CU size decision algorithm for HEVC intra coding

2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2016
This 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 CU size and mode decision algorithm for 3D-HEVC intercoding

Multimedia Tools and Applications, 2019
The 3D High Efficiency Video Coding (3D-HEVC) is an extension of the last 2D video coding generation (HEVC) using the Multi-view Video plus Depth map (MVD) format. In inter-coding process, the 3D-HEVC uses multiples inter prediction modes for each Coding Unit (CU) size. These prediction modes are performed to use all the possible CU sizes to select the

Machine learning-based fast CU size decision algorithm for 3D-HEVC inter-coding

Journal of Real-Time Image Processing, 2021
3D-high efficiency video coding (3D-HEVC) is an extension of the high efficiency video coding (HEVC) standard for the compression of the texture videos and depth maps. In 3D-HEVC inter-coding, the coding unit (CU) is recursively performed on variable sizes, namely, depth levels.

A Fast CU Size Decision Algorithm for the HEVC Intra Encoder

IEEE Transactions on Circuits and Systems for Video Technology, 2015
Intra coding plays a crucial role in the High Efficiency Video Coding (HEVC) standard. It provides the higher coding efficiency than the previous standard, H.264/Advanced Video Coding. The block partitioning in HEVC supports quad-tree-based coding unit (CU) structure from size $64 \times 64$ to $8 \times 8$ .

Fast CU Size and PU Partition Decision for AVS2 Intra Coding

2018 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2018
AVS2 is the new generation of video coding standard developed by the Audio Video Coding Standard Working Group of China. Similar to HEVC, a flexible partition structure is adopted to improve coding performance in AVS2. For intra coding, a coding unit (CU) is recursively split into sub CUs based on the quad-tree structure.

Early termination algorithm for CU size decision in HEVC intra coding

2015 9th Iranian Conference on Machine Vision and Image Processing (MVIP), 2015
Intra 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 ...

Texture-Based Fast CU Size Decision and Intra Mode Decision Algorithm for VVC

2019
Versatile Video Coding (VVC) is the next generation video coding standard. Compared with HEVC/H.265, in order to improve coding efficiency, its complexity of intra coding increases significantly. Too much encoding time makes it difficult for real-time coding and hardware implementation.

An effective CU size decision method for quality scalability in SHVC

Multimedia Tools and Applications, 2016
The Scalable extension of the High Efficiency Video Coding (known as SHVC) combines the high compression efficiency with the possibility of encoding different resolutions of the same encoded video in a single bitstream. However, this is accompanied with a high computational complexity.

A two-stage fast CU size decision method for HEVC intracoding

2015 IEEE 17th International Workshop on Multimedia Signal Processing (MMSP), 2015
In HEVC coding standard, the encoder employs a quad-tree-based Coding Unit (CU) structure to adapt to various texture characteristics of images. Although it provides better compression performance, the computation load increases drastically. In this paper, a two-stage fast CU size decision method is proposed for HEVC intra coding.
