Main paper

Supplement material

1. Basic requirements

  1. python >= 3.8

  2. pytorch = 1.9 (lower version may also be applicable.)

2. Prepare data

2.1 Training dataset

  1. Please download CAVE DATAset from https://www.cs.columbia.edu/CAVE/databases/multispectral/ for training. The image size is of 512*512*31.

  2. Crop training dataset. I randomly select 20 images for training and crop about 10000 patches of size 96*96*20. The corresponding MATLAB codes are in "data/gene_patches.m". (You could also freely choose your favourite way to crop patches.)

  3. Save the training dataset in path "dataroot"(your own data path).

2.2 Testing dataset

Please refer to "data/gene_test_data.m" file for creating your own test data using MATLAB. The noise generation methods in "data/utils" file are in consistent with those in "lib.py".

3. Training and testing

Plean refer to "train_hwnet.py" and "test.py" for training and testing HWLRMF. More test codes for NAILRMA, NGmeet, LLRT and their weighted versions will be uploaded soon.

4. Other information

4.1 SVD grad

For pytorch>=1.9, torch.linalg.svd could also be directly used. However, sometimes the grads could be numerically unstable.
