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

Hierarchical Intra Mode Decision for H.264/AVC

IEEE Transactions on Circuits and Systems for Video Technology, 2010
The intra mode prediction via exhaustive mode decision exploited in the H.264/advanced video coding effectively improves the coding efficiency, but at the expense of yielding higher computational complexity. In this letter, a fast intra mode decision algorithm, called the hierarchical intra mode decision (HIMD), is proposed to speed up the mode ...

Efficient Intra Mode Decision Via Statistical Learning

, 2007
Intra mode selection and motion estimation for spatial and temporal prediction play important roles for achieving high video compression ratio in the latest video coding standards, such as H.264/AVC. However, both components take most of the computational cost in the video encoding process.

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.

Adaptive stopping strategies for fast intra mode decision in HEVC

Journal of Visual Communication and Image Representation, 2018
Abstract Fast intra mode decision strategies are proposed to overcome the brute force mode decision for the coding unit (CU) in High Efficiency Video Coding (HEVC). The proposed work improves the rough-mode-decision (RMD) by initializing the candidate intra mode list using the fusion of the Hadamard-cost and the statistical-inference formed using ...

An efficient fast intra mode decision method based on orthogonal modes elimination

IEEE Transactions on Consumer Electronics, 2012
One of the computationally intensive stages in the H.264/AVC encoder is intra prediction. This is because rate-distortion optimization (RDO) is performed for the entire possible modes to select the optimum intra prediction mode. Fast intra mode decision methods have been introduced to reduce the number of tested modes by RDO to a few prediction modes ...

Fast CU size decision and mode decision algorithm for intra prediction in HEVC

Multimedia Tools and Applications, 2016
In the intra prediction process, High Efficiency Video Coding (HEVC) provides a quadtree-based coding unit (CU) block partitioning structure and up to 35 kinds of prediction modes to improve the coding performance. These technologies improve the coding efficiency significantly while the coding complexity is simultaneously increased rapidly as well.

A Fast Intra Mode Decision Method for HEVC

2020 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-Taiwan), 2020
The High Efficiency Video Coding (HEVC) standard can achieve approximately 50% bit-rate reduction that compares with H.264. To enhance intra coding efficiency in HEVC, an increase in the number of intra modes from 9 to 35 is adopted. However, this technique drastically increases computational complexity of intra mode selection.

Fast Intra Mode Decision for HEVC

2014 Tenth International Conference on Signal-Image Technology and Internet-Based Systems, 2014
The intra prediction in HEVC exploits the new techniques, such as the tree coding structure and up to 35 intra prediction modes, etc., to achieve high coding efficiency but incur heavy computational complexity as well. To reduce the computational complexity, a novel fast mode decision algorithm for intra prediction in HEVC is proposed in this paper. In
