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

• For a detailed understanding of our method, please refer to the paper: FusionMamba: Efficient Remote Sensing Image Fusion with State Space Model.
• This paper has been published in the IEEE Transactions on Geoscience and Remote Sensing (TGRS).

We expand the single-input Mamba block to accommodate dual inputs, creating the FusionMamba block, which can serve as a plug-and-play solution for information integration.

• Datasets for pansharpening: PanCollection. We recommend downloading datasets in the h5py format. The testing toolbox can be found here.

• 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.

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

• 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.
