Combining Progressive Rethinking and Collaborative Learning: A Deep Framework for In-Loop Filtering

no code implementations16 Jan 2020 Dezhao Wang, Sifeng Xia, Wenhan Yang, Jiaying Liu

For (2), we extract both intra-frame and inter-frame side information for better context modeling.

An Emerging Coding Paradigm VCM: A Scalable Coding Approach Beyond Feature and Signal

no code implementations9 Jan 2020 Sifeng Xia, Kunchangtai Liang, Wenhan Yang, Ling-Yu Duan, Jiaying Liu

To this end, we make endeavors in leveraging the strength of predictive and generative models to support advanced compression techniques for both machine and human vision tasks simultaneously, in which visual features serve as a bridge to connect signal-level and task-level compact representations in a scalable manner.

Deep Reference Generation with Multi-Domain Hierarchical Constraints for Inter Prediction

no code implementations16 May 2019 Jiaying Liu, Sifeng Xia, Wenhan Yang

In this paper, we address the problem by proposing a deep frame interpolation network to generate additional reference frames in coding scenarios.

A Group Variational Transformation Neural Network for Fractional Interpolation of Video Coding

no code implementations19 Jun 2018 Sifeng Xia, Wenhan Yang, Yueyu Hu, Siwei Ma, Jiaying Liu

Then a group variational transformation technique is used to transform a group of copied shared feature maps to samples at different sub-pixel positions.
