Direction-adaptive transforms for coding prediction residuals
TL;DR: These Direction-Adaptive Residual Transforms (DART) are shown to be more effective than the traditional 2-D DCT when coding residual blocks that contain directional features when coding prediction residuals of video.

Fast Motion and Disparity Estimation With Adaptive Search Range Adjustment in Stereoscopic Video Coding
TL;DR: An iterative motion and disparity estimation algorithm that can determine motion vectors of the right view and disparity vector of the current stereo pair in an iterative way and the speed-up gain of this iterative search is due to the use of a stereo-motion consistency constraint.

Deep Homography for Efficient Stereo Image Compression
TL;DR: In this paper, an end-to-end trainable deep network for stereo image compression (ESIC) is proposed, which uses a deep regression model to estimate the homography matrix, i.e., H matrix, and only the residual information between the left and right images is encoded.

Fast intra prediction for HEVC based on pixel gradient statistics and mode refinement
TL;DR: A Pixel Gradient Statistics (PGS) and Mode Refinement (MR) based fast mode decision algorithm that uses pixel gradient information to assist prediction mode selection after Rough Mode Decision (RMD).

In-loop filter using block-based filter control for video coding
TL;DR: A method of improving coding efficiency is proposed by using the Wiener filter as an in-loop filter that divides the decoded image into some fixed blocks, and decides whether to apply the filter for each block adaptively, so that the coding efficiency can be improved.
