Graph transform learning for image compression
TL;DR: A novel graph learning algorithm targeted for image compression that uncovers the connectivities between the pixels, by taking into consideration the coding of the image signal and the graph topology in rate-distortion terms.

Compression efficiency of the emerging video coding tools
TL;DR: A performance-based comparison between the JEM and HEVC reference software (HM) through an objective measurements and a subjective quality assessments shows that the J EM codec enables, subjectively, a quality enhancement up to 40% at similar low bit rates.

Fast Depth Map Intra Coding for 3D Video Compression-Based Tensor Feature Extraction and Data Analysis
TL;DR: This paper proposes fast depth map intra coding based on tensor feature extraction and data analysis and shows that the proposed intra model decision brings a good complexity reduction with negligible loss of rate distortion performance.

A Predictive Block-Size Mode Selection for Inter Frame in H.264
TL;DR: A predictive block-size selection algorithm to extraordinarily improve the encoding efficiency in H.264 using two efficient predictive methods: predictive skipping checking the sub-macroblock-level modes according to the sum of absolute difference of each macroblock and an adaptive threshold obtained from the mode information in the previous determined macroblock.

Light Field Compression Using Global Multiplane Representation and Two-Step Prediction
TL;DR: The recently proposed multiplane is used as the form of this global representation to predict a disparity-based global representation and the experimental results show the effectiveness of the proposed solution, and the better RD performance compared to other schemes especially under low bitrates.
