Extending HEVC by an affine motion model

TL;DR: Limiting the maximum block size to 16 × 16 samples, the average data rate reduction decreases to 0.1%, which proves synergy between the block size increase and the affine motion model.

CNN Oriented Complexity Reduction Of VVC Intra Encoder

TL;DR: This work reduces the block partitioning complexity of VTM6.1 through the use of Convolutional Neural Networks (CNNs), where each 64 × 64 Coding Unit (CU) is trained to predict a probability vector that speeds up coding block partitionsing in encoding.

Video Coding With Rate-Distortion Optimized Transform

TL;DR: Compared with the conventional DCT-based transform scheme adopted into the state-of-the-art H.264/AVC video coding standard, significant improvement of coding performance has been achieved for both intraframe and interframe coding with the proposed method.

Low-Complexity Mode Decision for MVC

TL;DR: A low complexity mode decision algorithm is proposed to reduce complexity of variable size motion estimation and disparity estimation in MVC and can significantly reduce computational complexity of MVC while maintaining almost the same RD performance.

ProxIQA: A Proxy Approach to Perceptual Optimization of Learned Image Compression

TL;DR: A proxy network is constructed, broadly termed ProxIQA, which mimics the perceptual model while serving as a loss layer of the network and is able to demonstrate a bitrate reduction of as much as 31% over MSE optimization, given a specified perceptual quality (VMAF) level.
