Fast Intra Mode Decision for HEVC
2014 Tenth International Conference on Signal-Image Technology and Internet-Based Systems, 2014The 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

Fast Intra size decision and mode decision algorithm for HEVC intra coding
2019 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM), 2019The latest High Efficiency Video Coding (HEVC) standard could achieve much higher coding efficiency than the current mainstream video coding standards (H.264/AVC). Compared with H.264/AVC, H.265 saves 50% cost than H.264/AVC at the same quality. But compression ratio gets improved with at least 2-4 times increase in computational complexity.

Fast PU Intra Mode Decision in Intra HEVC Coding
2019 Data Compression Conference (DCC), 2019As an upgrade for H.264/AVC, high efficiency video coding (HEVC) achieves 50% bitrate reduction under the equivalent visual quality. However, high computational complexity increases dramatically for adopting up to 35 intra prediction modes. To deal with this issue, we explore spatial-temporal correlation between PUs to narrow rough mode decision (RMD ...

Fast intra mode decision strategy for HEVC
2013 IEEE China Summit and International Conference on Signal and Information Processing, 2013This 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

An adaptive fast intra mode decision in HEVC
2012 19th IEEE International Conference on Image Processing, 2012Compared with H.264/AVC, the emerging video coding standard, High Efficiency Video Coding (HEVC), introduces a lots of intra prediction modes in intra coding, which brings a real challenge in practice. Although the Rough Mode Decision (RMD) scheme in HEVC provides a fast mode decision, it is a fixed strategy for different blocks with the same size and ...

Fast intra mode decision for HEVC intra coding
The 18th IEEE International Symposium on Consumer Electronics (ISCE 2014), 2014This paper proposes an adaptive intra mode selection algorithm with rough mode decision (RMD) stage and an early termination for rate-distortion optimization (RDO) stage for fast intra coding of High Efficiency Video Coding (HEVC). The proposed adaptive mode selection for fast intra coding employs the prediction modes from the upper layer of coding ...

A fast intra mode decision technique
2013 International Conference on Control Communication and Computing (ICCC), 2013A new method for intra mode decision (IMD) of blocks in video encoding, with possible neighbor pixel selection comprising of both source and reconstructed pixels, is presented. This new technique of selecting neighbouring luma and chroma pixels for efficient intra mode prediction has been tested on WebM Project libvpx (vpx-vp8, VP8 standard) reference ...

Adaptive Fast Mode Decision for HEVC Intra Coding
2016 International Conference on Digital Image Computing: Techniques and Applications (DICTA), 2016The latest High Efficiency Video Coding (HEVC) standard offers higher performance than existing video coding standards - up to 50% bit-rate reduction at the equal perceptual quality, but with a significant encoder complexity increase. With regard to intra prediction, a set of 35 intra prediction modes is defined in HEVC to enhance the intra coding ...

Improved fast intra mode decision with reliability refinement
2013 IEEE China Summit and International Conference on Signal and Information Processing, 2013Fast intra mode decision algorithms in video coding are very useful and necessary for practical real-time encoder implementation. It reduces the computational complexity by eliminating unlikely modes from candidate set. However, most of these algorithms may lead to the noticeable quality degradation, especially for the all intra coding scenario.
