UCVC: A Unified Contextual Video Compression Framework with Joint P-frame and B-frame Coding

no code implementations2 Feb 2024 Jiayu Yang, Wei Jiang, Yongqi Zhai, Chunhui Yang, Ronggang Wang

This paper presents a learned video compression method in response to video compression track of the 6th Challenge on Learned Image Compression (CLIC), at DCC 2024. Specifically, we propose a unified contextual video compression framework (UCVC) for joint P-frame and B-frame coding.

ConsistNet: Enforcing 3D Consistency for Multi-view Images Diffusion

1 code implementation16 Oct 2023 Jiayu Yang, Ziang Cheng, Yunfei Duan, Pan Ji, Hongdong Li

Given a single image of a 3D object, this paper proposes a novel method (named ConsistNet) that is able to generate multiple images of the same object, as if seen they are captured from different viewpoints, while the 3D (multi-view) consistencies among those multiple generated images are effectively exploited.

MLIC++: Linear Complexity Multi-Reference Entropy Modeling for Learned Image Compression

1 code implementation28 Jul 2023 Wei Jiang, Jiayu Yang, Yongqi Zhai, Feng Gao, Ronggang Wang

Additionally, to capture global contexts, we propose the linear complexity attention-based global correlations capturing by leveraging the decomposition of the softmax operation.

LLIC: Large Receptive Field Transform Coding with Adaptive Weights for Learned Image Compression

no code implementations19 Apr 2023 Wei Jiang, Peirong Ning, Jiayu Yang, Yongqi Zhai, Feng Gao, Ronggang Wang

To demonstrate the effectiveness of proposed transform coding, we align the entropy model to compare with existing transform methods and obtain models LLIC-STF, LLIC-ELIC, LLIC-TCM.

Non-parametric Depth Distribution Modelling based Depth Inference for Multi-view Stereo

1 code implementation CVPR 2022 Jiayu Yang, Jose M. Alvarez, Miaomiao Liu

Boundary pixels usually follow a multi-modal distribution as they represent different depths; Therefore, the assumption results in an erroneous depth prediction at the coarser level of the cost volume pyramid and can not be corrected in the refinement levels leading to wrong depth predictions.

Self-supervised Learning of Depth Inference for Multi-view Stereo

1 code implementation CVPR 2021 Jiayu Yang, Jose M. Alvarez, Miaomiao Liu

Here, we propose a self-supervised learning framework for multi-view stereo that exploit pseudo labels from the input data.
