Exploring Effective Priors and Efficient Models for Weakly-Supervised Change Detection

1 code implementation20 Jul 2023 Zhenghui Zhao, Lixiang Ru, Chen Wu

Specifically, change missing refer to the situation that the WSCD model fails to predict any changed pixels, even though the image-level label indicates changed, and vice versa for change fabricating.

Fast QTMT Partition for VVC Intra Coding Using U-Net Framework

no code implementations6 Apr 2023 Zhao Zan, Leilei Huang, Shushi Chen, Xiantao Zhang, Zhenghui Zhao, Haibing Yin, Yibo Fan

Experimental results demonstrate that our solution outperforms the state-of-the-art works with a complexity reduction of 44. 74% to 68. 76% and a BD-BR increase of 0. 60% to 2. 33%.

Thousand to One: Semantic Prior Modeling for Conceptual Coding

no code implementations12 Mar 2021 Jianhui Chang, Zhenghui Zhao, Lingbo Yang, Chuanmin Jia, Jian Zhang, Siwei Ma

To this end, we propose a novel end-to-end semantic prior modeling-based conceptual coding scheme towards extremely low bitrate image compression, which leverages semantic-wise deep representations as a unified prior for entropy estimation and texture synthesis.

Conceptual Compression via Deep Structure and Texture Synthesis

2 code implementations10 Nov 2020 Jianhui Chang, Zhenghui Zhao, Chuanmin Jia, Shiqi Wang, Lingbo Yang, Qi Mao, Jian Zhang, Siwei Ma

To this end, we propose a novel conceptual compression framework that encodes visual data into compact structure and texture representations, then decodes in a deep synthesis fashion, aiming to achieve better visual reconstruction quality, flexible content manipulation, and potential support for various vision tasks.

Image and Video Compression with Neural Networks: A Review

no code implementations7 Apr 2019 Siwei Ma, Xinfeng Zhang, Chuanmin Jia, Zhenghui Zhao, Shiqi Wang, Shanshe Wang

Deep convolution neural network (CNN) which makes the neural network resurge in recent years and has achieved great success in both artificial intelligent and signal processing fields, also provides a novel and promising solution for image and video compression.
