Installation

git clone https://github.com/YonghaoXu/SSUN

Dataset

Usage

  • Replace the file path for the hyperspectral data in HyperFunctions.py with yours.
  • Run SSUN.py.
  • Change the s1s2 index in SSUN.py to switch from different grouping strategies.
    • Left: Strategy 1 s1s2 = 1
    • Right: Strategy 2 s1s2 = 2

Note

  • 12/2019: Update the code with the Tensorflow backend engine.
