Quadtree Degeneration for HEVC

IEEE Transactions on Multimedia, 2016
The quadtree is one of the most advanced techniques contributing to the excellent compression performance of high efficiency video coding (HEVC). However, the computational complexity increases because the quadtree examines all coding unit (CU) sizes to obtain the optimal CU partitioning.

An Overview of Tiles in HEVC

IEEE Journal of Selected Topics in Signal Processing, 2013
Tiles is a new feature in the High Efficiency Video Coding (HEVC) standard that divides a picture into independent, rectangular regions. This division provides a number of advantages. Specifically, it increases the “parallel friendliness” of the new standard by enabling improved coding efficiency for parallel architectures, as compared to previous ...

Introduction to the Special Issue on HEVC Extensions and Efficient HEVC Implementations

IEEE Transactions on Circuits and Systems for Video Technology, 2016
High Efficiency Video Coding (HEVC) is the most recent standard in the series of major video coding standards jointly produced by the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). HEVC was first approved in 2013 in the ITU-T as Recommendation H.265 and in ISO/IEC as International Standard 23008-2, and it ...

Frame-Wise CNN-Based Filtering for Intra-Frame Quality Enhancement of HEVC Videos

IEEE transactions on circuits and systems for video technology (Print), 2021
The paper proposes a novel frame-wise filtering method based on Convolutional Neural Networks (CNNs) for enhancing the quality of HEVC decoded videos. A novel deep neural network architecture is proposed for post-filtering the entire intra-coded videos ...

Content-Aware Tunable Selective Encryption for HEVC Using Sine-Modular Chaotification Model

IEEE transactions on multimedia
Existing High Efficiency Video Coding (HEVC) selective encryption algorithms only consider the encoding characteristics of syntax elements to keep format compliance, but ignore the semantic features of video content, which may lead to unnecessary ...

Transform Coding Techniques in HEVC

IEEE Journal of Selected Topics in Signal Processing, 2013
High Efficiency Video Coding (HEVC) is the most recent jointly developed video coding standard of ITU-T Visual Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG). Although its basic architecture is built along the conventional hybrid block-based approach of combining prediction with transform coding, HEVC includes a number of ...

Sample adaptive offset for HEVC

2011 IEEE 13th International Workshop on Multimedia Signal Processing, 2011
A new video coding tool, sample adaptive offset (SAO), is introduced in this paper. SAO has been adopted into the Working Draft of the new video coding standard, High-Efficiency Video Coding (HEVC). The SAO is located after deblocking in the video coding loop.
