Shearlet Transform-Based Light Field Compression Under Low Bitrates
TL;DR: This paper presents a novel compression scheme for LF data captured using multiple traditional cameras, and demonstrates that incorporating the residual information into the compression scheme increased the overall peak signal to noise ratio (PSNR) by 2 dB.
Journal ArticleDOI
Attention-Based Dual-Scale CNN In-Loop Filter for Versatile Video Coding
TL;DR: An architecture named as ADCNN with an attention based processing block is proposed to reduce artifacts of I frames and B frames, which take advantage of informative priors such as the quantization parameter (QP) and partitioning information.
Proceedings ArticleDOI
Efficiency improvements for a geometric-partition-based video coder
TL;DR: This work presents a motion vector prediction scheme based on directional partitions and presents a method for complexity reduction based on the most frequent partitions, showing that it is possible to still produce good coding gains with lower complexity than previous approaches.
Proceedings ArticleDOI
Transforms for the motion compensation residual
Fatih Kamisli,Jae Lim +1 more
TL;DR: In this paper, the authors proposed a set of block transforms for the motion compensation residual (MC-residual) that can improve the compression efficiency of the MC-resolution.

Context-based entropy coding in AVS video coding standard
TL;DR: The experimental results demonstrate that both C2DVLC and CBAC can achieve comparable or even slightly higher coding performance when compared to Context-Adaptive Variable Length Coding (CAVLC) in H.264/AVC baseline profile and Context-Based Adaptive Binary Arithmetic Coded (CABAC) in CABAC main profile respectively.
