This demo is using NRR algorithm to HSI denoising. When you use this demo, you can directly run the function "NRR_HSI_Denoising_Demo.m". Currenly, this demo can be effectively used to test two datasets, including the CAVE dataset, and the WDC dataset. If you have any question, please connect Dr. Zha Zhiyuan.
