Spatial Decomposition and Temporal Fusion based Inter Prediction for Learned Video Compression

no code implementations29 Jan 2024 Xihua Sheng, Li Li, Dong Liu, Houqiang Li

With the SDD-based motion model and long short-term temporal contexts fusion, our proposed learned video codec can obtain more accurate inter prediction.

Offline and Online Optical Flow Enhancement for Deep Video Compression

no code implementations11 Jul 2023 Chuanbo Tang, Xihua Sheng, Zhuoyuan Li, Haotian Zhang, Li Li, Dong Liu

In the offline stage, we fine-tune a trained optical flow estimation network with the motion information provided by a traditional (non-deep) video compression scheme, e. g. H. 266/VVC, as we believe the motion information of H. 266/VVC achieves a better rate-distortion trade-off.

VNVC: A Versatile Neural Video Coding Framework for Efficient Human-Machine Vision

no code implementations19 Jun 2023 Xihua Sheng, Li Li, Dong Liu, Houqiang Li

Such compact representations need to be decoded back to pixels before being displayed to humans and - as usual - before being enhanced/analyzed by machine vision algorithms.

Attribute Artifacts Removal for Geometry-based Point Cloud Compression

no code implementations1 Dec 2021 Xihua Sheng, Li Li, Dong Liu, Zhiwei Xiong

In this paper, we propose a Multi-Scale Graph Attention Network (MS-GAT) to remove the artifacts of point cloud attributes compressed by G-PCC.

Temporal Context Mining for Learned Video Compression

1 code implementation27 Nov 2021 Xihua Sheng, Jiahao Li, Bin Li, Li Li, Dong Liu, Yan Lu

From the stored propagated features, we propose to learn multi-scale temporal contexts, and re-fill the learned temporal contexts into the modules of our compression scheme, including the contextual encoder-decoder, the frame generator, and the temporal context encoder.
