Hyperspectral Image Classification

Hyperspectral Image Classification

Welcome to my HomePage

This repository implementates 6 frameworks for hyperspectral image classification based on PyTorch and sklearn.

The detailed results can be seen in the Classification of Hyperspectral Image Based on Double-Branch Dual-Attention Mechanism Network.

Some of our code references the projects

If our code is helpful to you, please cite
Li R, Zheng S, Duan C, et al. Classification of Hyperspectral Image Based on Double-Branch Dual-Attention Mechanism Network[J]. Remote Sensing, 2020, 12(3): 582.

Requirements:

numpy >= 1.16.5
PyTorch >= 1.3.1
sklearn >= 0.20.4

Datasets:

You can download the hyperspectral datasets in mat format at: http://www.ehu.eus/ccwintco/index.php/Hyperspectral_Remote_Sensing_Scenes, and move the files to ./datasets folder.

Usage:

  1. Set the percentage of training and validation samples by the load_dataset function in the file ./global_module/generate_pic.py.
  2. Taking the DBDA framework as an example, run ./DBDA/main.py and type the name of dataset.
  3. The classfication maps are obtained in ./DBDA/classification_maps folder, and accuracy result is generated in ./DBDA/records folder.

Network:

Figure 1. The structure of the DBDA network. The upper Spectral Branch composed of the dense spectral block and channel attention block is designed to capture spectral features. The lower Spatial Branch constituted by dense spatial block, and spatial attention block is designed to exploit spatial features.
