An efficient intra-mode decision method for HEVC
Signal, Image and Video Processing, 2016This paper proposes a new intra-mode decision method for HEVC. The proposed method makes use of the characteristics of some special modes that belong to both rough mode decision mode set and most probable mode set. It also improves the coding efficiency by adaptively applying different algorithms depending on the prediction unit size. Not only the luma

Fast Intra-Mode and CU Size Decision for HEVC
IEEE Transactions on Circuits and Systems for Video Technology, 2017The 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, 2010The 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 ...

Fast CU size decision and mode decision algorithm for HEVC intra coding
IEEE Transactions on Consumer Electronics, 2013The 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, 2018Abstract 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, 2012One 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, 2016In 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), 2020The 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.
