Deep Co-supervision and Attention Fusion Strategy for Automatic COVID-19 Lung Infection Segmentation on CT Images

2 code implementations20 Dec 2021 Haigen Hu, Leizhao Shen, Qiu Guan, Xiaoxin Li, Qianwei Zhou, Su Ruan

In this paper, a novel segmentation scheme is proposed for the infections of COVID-19 by enhancing supervised information and fusing multi-scale feature maps of different levels based on the encoder-decoder architecture.

Adaptively Customizing Activation Functions for Various Layers

1 code implementation17 Dec 2021 Haigen Hu, Aizhu Liu, Qiu Guan, Xiaoxin Li, ShengYong Chen, Qianwei Zhou

To enhance the nonlinearity of neural networks and increase their mapping abilities between the inputs and response variables, activation functions play a crucial role to model more complex relationships and patterns in the data.

Image Denoising Using Sparsifying Transform Learning and Weighted Singular Values Minimization

no code implementations2 Apr 2020 Yanwei Zhao, Ping Yang, Qiu Guan, Jianwei Zheng, Wanliang Wang

By taking both advantages of image domain and transform domain in a general framework, we propose a sparsity transform learning and weighted singular values minimization method (STLWSM) for IDN problems.
