This is the code for ``Quaternion Dictionary Learning and Satuation-Value 
Total Variation-based Color Image Restoration'',  in IEEE Transactions on Multimedia, doi: 10.1109/TMM.2021.3107162.
with Gaussian blur (15,1) and Gaussian noise 12.75.

%%%%%%%%%
Run main.m  to test the results.

madeblur.m is to generate the degraded images.

dict_256_atoms.mat is the trained dictionary with 800 images of Dataset DIV2K.
If you need to retrain the dic, pleace see dic.m

0804_15_1_12.75.mat is generated from made blur.m

0804.png is the original image from DIV2K.

The cropped image is for parameter setting, in the real test, we test the full image.
