HEVC Transform and Quantization
2014This chapter provides an overview of the transform and quantization design in HEVC. HEVC specifies two-dimensional transforms of various sizes from 4 × 4 to 32 × 32 that are finite precision approximations to the discrete cosine transform (DCT). In addition, HEVC also specifies an alternate 4 × 4 integer transform based on the discrete sine transform ...

An HEVC bitstream consists of a sequence of data units called network abstraction layer (NAL) units. Some NAL units contain parameter sets that carry high-level information regarding the entire coded video sequence or a subset of the pictures within it.

Saliency based perceptual HEVC
2014 IEEE International Conference on Multimedia and Expo Workshops (ICMEW), 2014Saliency represents the probability of human attention over the image therefore is important in understanding the importance of different areas in the image. In this paper, we consider how to utilize the saliency information in HEVC video coding. The graph-based visual saliency is incorporated with the quantization control in HEVC to reduce the bit ...

Multi-Intensity Illuminated Infrared video compression using MV-HEVC and 3D-HEVC
2017 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2017Multi-Intensity Illuminated Infrared (MIIR) video is a new type of infrared video which solves the problem of improper illumination conditions for ordinary infrared cameras for nighttime surveillance. However, its time-varying intensity makes it hard to be compressed with traditional video coding methods.

Journal of Real-Time Image Processing, 2015
The increasing demand for real-time applications with high and ultra-high-definition video urged the ITU-T and the ISO/IEC to join their forces to develop the next-generation video coding standard. The new coding standard that has been produced is known as High-Efficiency Video Coding (HEVC).

Introduction to the Special Issue on HEVC Extensions and Efficient HEVC Implementations
IEEE Transactions on Circuits and Systems for Video Technology, 2016High 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 ...

An Adaptive Stereoscopic Video Streaming Mechanism Using MV-HEVC and 3D-HEVC Technologies
2019 Twelfth International Conference on Ubi-Media Computing (Ubi-Media), 2019In this paper, we propose an adaptive stereoscopic video streaming mechanism using MV-HEVC and 3D-HEVC technologies. When the current available bandwidth is insufficient for delivering all video layers, the mechanism selects the MV-HEVC and 3D-HEVC video pictures near the current playing point with the proposed rate control algorithm.

Efficient SBT Architecture for HEVC
2020In this paper report a different VLSI area efficient integer transform is designed for the High Efficiency video coding (HEVC) encoder. This integer transform built depends on Signed Biplane Transform (SBT) matrix. Which are extracted from the bit plane slicing of the integer transform grids in HEVC.
