Piecewise DC prediction in HEVC

Signal Processing: Image Communication, 2014
In this paper, we propose an improved DC prediction method for high-efficiency video coding (HEVC) intra coding. The technique involves the application of pixel-wise predictors rather than block-based predictor in the DC mode. In HEVC, the pixels of neighboring reconstructed blocks are used to support multiple directional spatial prediction modes and ...

Bilateral adaptive quantization in HEVC

Multimedia Tools and Applications, 2018
In this paper, we proposed an adaptive quantization algorithm for High Efficiency Video Coding (HEVC) to boost the encoding performance. The transform coefficients in a Transform Unit (TU) inherit the energy concentration property. However, they are equally quantized before entropy coding.

Inter-Block Dependency-Based CTU Level Rate Control for HEVC

IEEE transactions on broadcasting, 2020
Although high efficiency video coding (HEVC) has achieved high coding performance, it has been shown that dependent rate-distortion optimization (RDO) can still further improve the coding performance at the encoder side.

Spatially Scalable Video Coding For HEVC

IEEE Transactions on Circuits and Systems for Video Technology, 2012
Spatially scalable video coding (SSVC) provides an efficient way to transmit one video at different resolutions. Based on the emerging High Efficiency Video Coding (HEVC), we propose an SSVC scheme to support both single-loop (SL) and multiloop (ML) solutions by enabling different interlayer prediction mechanisms. Specifically, we employ two interlayer

Machine Learning-Based Fast Intra Mode Decision for HEVC Screen Content Coding via Decision Trees

IEEE transactions on circuits and systems for video technology (Print), 2020
The screen content coding (SCC) extension of high efficiency video coding (HEVC) improves coding gain for screen content videos by introducing two new coding modes, namely, intra block copy (IBC) and palette (PLT) modes.

Extensions to HEVC

2014
In this chapter, a survey of the currently ongoing activities for extension of the HEVC specification is provided. As these activities are beyond the scope of this book and have not been finalized by the time of writing, the presentation is kept at a higher level.

A New Optimization Algorithm for HEVC

2015
In this paper, we propose a new optimization algorithm utilizing the texture feature and correlation of adjacent frames for newly proposed video standard High Efficiency Video Coding (HEVC). For intra prediction, the complexity of pictures’ texture to perform different levels of simplification on Most Probable Mode (MPM) selection is scaled.

Analysis and Evaluation of HEVC

Applied Mechanics and Materials, 2014
HEVC video coding standard is the next generation of H.264 coding standard, which is able to achieve twice coding efficiency compared with H.264/AVC High Profile. This paper analyzes the key features of HEVC standard based on HEVC reference software HM12.0. Experiments cover different resolutions ranging from 240p to 1600p.
