The proposed method uses an untrained lightweight deep model, initialized with some weight initialization strategy for feature extraction from bi-temporal hyperdimensional images.

To run the code please download the datasets and put them in datasets folder.
Then cd to deepImagePriorNonlinear directory and run the code for Santa Barbara dataset by using following command:
python deepImagePriorSantaBarbara.py --manualSeed 40
The manual seed can be varied.

If you find this code useful, please consider citing:
