FusionMamba

• Code for the paper: "FusionMamba: Efficient Image Fusion with State Space Model", 2024.

• First application of the state space model (SSM) in the hyper-spectral pansharpening and hyper-spectral image super-resolution (HISR) tasks.

• State-of-the-art (SOTA) performance in pansharpening, hyper-spectral pansharpening, and HISR tasks.

Paper

• For a detailed understanding of our method, please refer to the arxiv version of this paper: FusionMamba: Efficient Image Fusion with State Space Model.
• This paper has been accepted by the IEEE Transactions on Geoscience and Remote Sensing.

Get Started

Dataset

• Datasets for pansharpening: PanCollection. We recommend downloading datasets in the h5py format.

• Datasets for hyper-spectral pansharpening: HyperPanCollection. We recommend downloading datasets in the h5py format.

• Dataset for HISR: the CAVE dataset. You can find this dataset on the Internet.

Installation

1. Clone the repository:

git clone https://github.com/PSRben/FusionMamba.git

2. Install the Mamba implementation by following the instructions in the Mamba-block directory.

3. Install other packages:

pip install einops h5py opencv-python torchinfo scipy numpy

Usage

• This repository is only for the pansharpening task.

• The model weights trained on the WV3 dataset for 400 epochs can be found in the weights directory.

# train
python train.py --train_data_path ./path_to_data/train_WV3.h5 --val_data_path ./path_to_data/valid_WV3.h5
# test
python test.py --file_path ./path_to_data/name.h5 --save_dir ./path_to_dir --weight ./weights/epochs.pth
