Steps to run the program

• Clone/Download_Zip the repository
• Open MATLAB and connect to the folder Similarity_Matrices
• Modify the code for your input hyperspectral image
• Run any of the codes in the folder for computing the similarity/Adjacency matrix.
• Now connect to the folder Main
• Modify the inputs accordingly and run Sparse_SpectralClustering.m or Spectral_Clustering.m
