Pan-Mamba

This folder contains the implementation of the Pan-Mamba model for pan-sharpening.

We have released pre-trained checkpoints for Pan-Mamba, trained on the WV2, WV3, and Gaofen-2 satellites. The checkpoints trained on 4 channels (RGB and Near-Infrared) images. Please note that the training datasets are not currently public. You are encouraged to test the checkpoints on your own satellite datasets.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

In order to run this implementation, you need to have the following software and libraries installed:

  • Python 3.7 or later
  • PyTorch 1.6 or later
  • CUDA (if using GPU)
  • NumPy
  • Matplotlib
  • OpenCV
  • PyYAML

Installing

Please follow the https://github.com/alexhe101/Pan-Mamba/blob/main/Mamba-block/readme.md to install mamba block first.

You can install the necessary packages using pip:

pip install torch numpy matplotlib opencv-python pyyaml

Configuration

Before training the model, you need to configure the following options in the option.yaml file:

  • log_dir: the directory to store the training log files.
  • checkpoint: the directory to store the trained model parameters.
  • data_dir_train: the directory of the training data.
  • data_dir_eval: the directory of the evaluation data.

Training the Model

To train the model, you can run the following command:

python main.py

Testing the Model

To test the trained MSDDN model, you can run the following command:

python test.py
python py-tra/demo_deep_methods.py

  • pre_folder: The location where the pretrained models are stored.

Testing

  • algorithm: The algorithm to use for testing.
  • type: The type of testing, either test or eval.
  • data_dir: The location of the test data.
  • source_ms: The source of the multi-spectral data.
  • source_pan: The source of the panchromatic data.
  • model: The location of the model to use for testing.
  • save_dir: The location to save the test results.

Data Processing

  • upscale: The upscale factor.
  • batch_size: The size of each batch.
  • patch_size: The size of each patch.
  • data_augmentation: Whether to use data augmentation.
