High-efficiency parallelism solution for a Multiview High-Efficiency Video Coding decoder

Journal of Parallel and Distributed Computing, 2020
Abstract Thus far, Multiview High-Efficiency Video Coding (MV-HEVC) can only use a central processing unit (CPU) to perform decompression on a personal computer (PC) or workstation. Because MV-HEVC is much more complex than High-Efficiency Video Coding (HEVC), decompressors need higher parallelism to decompress in real time.

On transform dynamic range in high efficiency video coding

2012 19th IEEE International Conference on Image Processing, 2012
We consider the problem of determining the dynamic range of an inverse transform. An analytic approach is described, and the resulting bound is a function of the bit-depth of the input data and the maximum L 1 norm of the transformation matrix. Furthermore, the analytic approach is refined to account for nonlinearities within a transform due to ...

Improving Intra Prediction in High-Efficiency Video Coding

IEEE Transactions on Image Processing, 2016
Intra prediction is an important tool in intra-frame video coding to reduce the spatial redundancy. In current coding standard H.265/high-efficiency video coding (HEVC), a copying-based method based on the boundary (or interpolated boundary) reference pixels is used to predict each pixel in the coding block to remove the spatial redundancy.

Fast Intra Coding Implementation for High Efficiency Video Coding (HEVC)

2017 Data Compression Conference (DCC), 2017
In High Efficiency Video Coding (HEVC), a quad-tree based Coding Unit (CU) partitioning scheme is employed, achieving a substantial improvement in coding efficiency compared with previous standards. The superior coding efficiency of HEVC is achieved at the expense of greatly increased complexity.

A novel distortion model for quadtree coding in high efficiency video coding

SPIE Proceedings, 2012
In this paper, a novel distortion model based on a mixture of Laplacian distributions is presented for the transform coefficients of predicted residues in quadtree coding. The mixture Laplacian distribution is made on the coding structure with different quadtree coding unit (CU) depth.

Predictive coding of intra prediction modes for high efficiency video coding

2012 Picture Coding Symposium, 2012
The High Efficiency Video Coding (HEVC) standardization process currently underway includes many tools for the coding of intra pictures. HEVC allows for many more intra prediction modes or directions as compared to previous standards. Efficient coding of these modes is therefore important because the modes consume a non-negligible portion of the total ...

Fast and efficient inter CU decision for high efficiency video coding

2014 IEEE International Conference on Image Processing (ICIP), 2014
In this paper, a graph cut based fast Coding Unit (CU) decision algorithm is proposed for HEVC inter frames. Firstly, a feature called pyramid variance of the absolute difference (PVAD) is designed for the CU selection. Secondly, the CU decision is modeled as a Markov Random Field (MRF) inference problem, which can be optimized by the graph cut ...
