Context adaptive mode sorting for fast HEVC mode decision

2015 IEEE International Conference on Image Processing (ICIP), 2015
Typical H.265/High Efficiency Video Coding (HEVC) encoder implementations test a variety of prediction modes and select the optimal configuration for each block in terms of Rate-Distortion (RD) cost. A fast HEVC mode decision algorithm is proposed here referred to as Context Adaptive Mode Sorting (CAMS). The frequency of selection of modes and their RD

A Novel Fast Mode Decision Algorithm for AVS2 Intra Coding

IEEE International Conference on Signal and Image Processing, 2019
AVS2 is the latest generation of video coding standard independently developed by China. Compared with the most popular international standard HEVC/H.265, AVS2 achieves the same level of compression efficiency, which doubled in compression efficiency ...

Fast macroblock mode decision in H.264

2004 IEEE Region 10 Conference TENCON 2004., 2004
This paper proposes a fast 16/spl times/16 macroblock (MB) mode decision algorithm, which skips variable block size motion estimation/compensation and spatial-predictive coding in H.264 video coding standard. In experimental results, the encoder using the proposed method runs about 2.76 times as fast as that using H.264 rate-distortion optimization ...

Research on fast mode decision for AVS

2012 3rd International Conference on System Science, Engineering Design and Manufacturing Informatization, 2012
This electronic docume AVS is domestic Audio Video-coding Standard series standards. AVS emploies RDO technique in mode decision, but traversal mode increase computational complexity. In order to reduce model number, the paper proposes a SKIP mode decision algorithm, fast inter mode decision and selective Intra mode decision.

Fast intra mode decision strategy for HEVC

2013 IEEE China Summit and International Conference on Signal and Information Processing, 2013
This paper proposes a fast intra prediction mode decision strategy for HEVC (High Efficiency Video Coding), which aiming at reducing computation time and keeping the coding performance at the same time. Using a notation of a circle, we arrange the candidate modes into different groups. The order of processing MPM(most probable modes) and RMD(rough mode

Fast Inter Mode Decision Algorithms for x265

2018 IEEE 4th Information Technology and Mechatronics Engineering Conference (ITOEC), 2018
The latest High-Efficiency Video Coding (HEVC) standard achieves nearly 50% bit rates reduction for similar quality relative to H.264/Advanced Video Coding(AVC) . However, its complexity is enormously increased ,which becomes one of the most challenges for its deployment in real time applications.

Fast mode decision for multiview video coding

2009 16th IEEE International Conference on Image Processing (ICIP), 2009
In the draft of multi-view coding (MVC), variable size motion estimation and disparity estimation are employed to select the best coding mode for each macroblock. These techniques achieve the highest possible coding efficiency, but they result in extremely large computation complexity which obstructs MVC from practical application.

Fast Mode Decision In Hevc Intra Prediction, Using Region Wise CNN Feature Classification

2018 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2018
The computational time of HEVC encoder is increased mainly because of hierarchical quadtree based structure, recursive search for finding best coding units (CU), and the exhaustive prediction mode search upto 35.
