Model-based cellular kinetic analysis of SARS-CoV-2 infection: different immune response modes and treatment strategies

no code implementations12 Jan 2021 Zhengqing Zhou, Zhiheng Zhao, Shuyu Shi, Jianghua Wu, Dianjie Li, Jianwei Li, Jingpeng Zhang, Ke Gui, Yu Zhang, Heng Mei, Yu Hu, Qi Ouyang, Fangting Li

Integrating theoretical results with clinical COVID-19 patients' data, we classified the COVID-19 development processes into three typical modes of immune responses, correlated with the clinical classification of mild & moderate, severe and critical patients.

Learning a Single Model with a Wide Range of Quality Factors for JPEG Image Artifacts Removal

1 code implementation15 Sep 2020 Jianwei Li, Yongtao Wang, Haihua Xie, Kai-Kuang Ma

Our proposed network is a single model approach that can be trained for handling a wide range of quality factors while consistently delivering superior or comparable image artifacts removal performance.

Balance Scene Learning Mechanism for Offshore and Inshore Ship Detection in SAR Images

no code implementations21 Jul 2020 Tianwen Zhang, Xiaoling Zhang, Jun Shi, Shunjun Wei, Jianguo Wang, Jianwei Li, Hao Su, Yue Zhou

Huge imbalance of different scenes' sample numbers seriously reduces Synthetic Aperture Radar (SAR) ship detection accuracy.

Conformal and Low-Rank Sparse Representation for Image Restoration

no code implementations ICCV 2015 Jianwei Li, Xiaowu Chen, Dongqing Zou, Bo Gao, Wei Teng

In this paper, we propose a novel sparse representation approach called conformal and low-rank sparse representation (CLRSR) for image restoration problems.

Sparse Dictionary Learning for Edit Propagation of High-Resolution Images

no code implementations CVPR 2014 Xiaowu Chen, Dongqing Zou, Jianwei Li, Xiaochun Cao, Qinping Zhao, Hao Zhang

Previous approaches for edit propagation typically employ a global optimization over the whole set of image pixels, incurring a prohibitively high memory and time consumption for high-resolution images.
