Effective CU Size Decision for HEVC Intracoding

IEEE Transactions on Image Processing, 2014
In high efficiency video coding (HEVC), the tree structured coding unit (CU) is adopted to allow recursive splitting into four equally sized blocks. At each depth level (or CU size), it enables up to 35 intraprediction modes, including a planar mode, a dc mode, and 33 directional modes.

A Fast CU Size Decision Algorithm for HEVC

IEEE Transactions on Circuits and Systems for Video Technology, 2015
High Efficiency Video Coding (HEVC) employs a coding unit (CU), prediction unit (PU), and transform unit (TU) based on the quadtree coding tree unit (CTU) structure to improve coding efficiency. However, the computational complexity increases greatly because the rate-distortion (RD) optimization process should be performed for all CUs, PUs, and TUs to ...

Accelerated CU decision based on enlarged CU sizes for HEVC UHD videos

2016 IEEE International Conference on Signal and Image Processing (ICSIP), 2016
High Efficiency Video Coding (HEVC) is the latest video coding standard and has achieved 50% better compression performance compared to prior video standards competing with (2K, 4K, and 8K) video resolutions. HEVC adopts flexible quad-tree structure, resulting 60% of inter prediction complexity.

Fast CU size decision and mode decision algorithm for HEVC intra coding

IEEE Transactions on Consumer Electronics, 2013
The emerging international standard of High Efficiency Video Coding (HEVC) is a successor to H.264/AVC. In the joint model of HEVC, the tree structured coding unit (CU) is adopted, which allows recursive splitting into four equally sized blocks. At each depth level, it enables up to 34 intra prediction modes.

Fast Intra-Mode and CU Size Decision for HEVC

IEEE Transactions on Circuits and Systems for Video Technology, 2017
The latest video coding standard High Efficiency Video Coding (HEVC) achieves about a 50% bit-rate reduction compared with H.264/AVC under the same perceptual video quality. For intra coding, a coding unit (CU) is recursively divided into a quadtree-based structure from the largest CU $64 \times 64$ to the smallest CU $8 \times 8$ . Also, up

A Spatiotemporal Content-Based CU Size Decision Algorithm for HEVC

IEEE Transactions on Broadcasting, 2020
The high efficiency video coding (HEVC) standard provides superior efficiency for encoding and improves the compression ratio by almost 50% compared with previous video coding standards, such as advanced video coding (AVC). However, more intensive computation complexity is introduced by implementing the flexible quad tree-structured coding model.
