Experiments: to run a representative example of the real data experiments reported in the article, configure and run the main_real_data.m script. The script main_extract_data.m can be used to extract the hyperspectral data from the raw data file included in the data/raw_data folder. A .mat file obtained after data extraction is already provided in the data folder.
Dependencies: the present codes includes MATLAB functions described in the following publications, and developed by their respective authors.
