# Description

This repository contains the pre-trained diffusion models
associated to the Denoising Diffusion Probabilistic Models
(DDPM-CD) developed by Wele Gedara Chaminda Bandara, Nithin
Gopalakrishnan Nair, Vishal M. Patel.

The optimized model is for unsupervised hyperspectral image
restoration (HIRDiff) is developed by Li Pang, Xiangyu Rui,
Long Cui, Hongzhong Wang, Deyu Meng, Xiangyong Cao.
