MAC-Net: Model Aided Nonlocal Neural Network for Hyperspectral Image Denoising

open access: yes, 2021
Hyperspectral image (HSI) denoising is an ill-posed inverse problem. The underlying physical model is always important to tackle this problem, which is unfortunately ignored by most of the current deep learning (DL)-based methods, producing poor ...
