Packages for a benchmarking protocol for SAR colorization which contains a protocol for generating ground truth, data analysis algorithm, three spectral-based solutions, three deep-learning-based solutions, metrics, and performance inspections.
- "filepath_gen.py" is for generating the file path of the dataset. The last null string should be deleted manually.
- "gt_ihs_gen.m" is for generating ground truth images through the GIHS algorithm.
- codes for three spectral-based solutions, namely NoColSAR, LR4ColSAR, and NL4ColSAR.
- there is also a code for data analysis through scatter plots between the SAR band and the band of ground truth.
- codes for spatial-spectral-based solution CNN4ColSAR.
- a test model file is also contained.
- codes for solution DivColSAR.
- codes for solution cGAN4ColSAR.
- saved models of the proposed approaches for reproducibility.

- Matlab codes for Q2n.
- python codes for SAM and NRMSE.
- Matlab code for data analysis between colorized SAR image and ground truth.
- python code for residual image comparison.
- there are 4 train samples and 4 test samples.
- the whole train dataset can be downloaded by the following Baidu Netdisk link: https://pan.baidu.com/s/1xHSDNXoQzo5xewMsjQCBrA?pwd=2h7y, password：2h7y. You can also use the link: https://terabox.com/s/1J2mTvAROV9SSzilUkwsgeg
- it is noted that the sar_train and opt_train are divided into several parts because of some restrictions, so the users can merge them after decompression. Additionally, sar_train_20, opt_train_20, and gt_train_20 are the trainset for LR4ColSAR and NL4ColSAR.
