Features
The library consist basically of the following python modules:
- PolSAR image manipulation: pseudocolor image generation, force SPD.
- PolSAR datasets: San Francisco Bay, Flevoland and Foulum. Train/test splits generation, manual selection of training points. Accuracy and Confusion Matrix computation.
- Smoothing algorithms: Potts, Graph Cut and Maximun.
- Unary potential generation from Complex Wishart, Real Wishart Mixture and FV (RWM based).
Dependencies
- matplotlib
- numpy
pystruct -> https://pystruct.github.io/
scikit-image -> http://scikit-image.org/
scikit-learn -> scikit-learn.org/
- scipy
