Abstract: Recent years have witnessed great progress in image restoration thanks to the advancements in modern deep neural networks e.g. Convolutional Neural Network and Transformer. However, existing restoration backbones are usually limited due to the inherent local reductive bias or quadratic computational complexity. Recently, Selective Structured State Space Model e.g., Mamba, have shown great potential for long-range dependencies modeling with linear complexity, but it is still under-explored in low-level computer vision. In this work, we introduce a simple but strong benchmark model, named MambaIR, for image restoration. In detail, we propose the Residual State Space Block as the core component, which employs convolution and channel attention to enhance capabilities of the vanilla Mamba. In this way, our MambaIR takes advantages of local patch recurrence prior as well as channel interaction to produce restoration-specific feature representation. Extensive experiments demonstrate the superiority of our method, for example, MambaIR outperforms Transformer-based baseline SwinIR by up to 0.36dB, using similar computational cost but with global receptive field.

./analysis/
😄thop
library has a bug, which was also discussed in #issue44. We have updated the new accurate calculation code which uses fvcore
and additionally registers the previous missing parameters. You can use this new code in ./analysis/flops_param_fvcore.py
for complexity analysis. Note that the model complexity obtained from this code is lager than the reported one. We will release a new comparable MambaIR-light model soon, stay tuned!Model | Task | Test_dataset | PSNR | SSIM | model_weights | log_files |

We achieve state-of-the-art performance on various image restoration tasks. Detailed results can be found in the paper.
This codebase was tested with the following environment configurations. It may work with other versions.
To use the selective scan with efficient hard-ware design, the mamba_ssm
library is needed to install with the folllowing command.
pip install causal_conv1d==1.0.0
pip install mamba_ssm==1.0.1
One can also create a new anaconda environment, and then install necessary python libraries with this requirement.txt and the following command:
conda install --yes --file requirements.txt
One can also reproduce the conda environment with the fllowing simple commands (cuda-11.7 is used, you can modify the yaml file for your cuda version):
cd ./MambaIR
conda env create -f environment.yaml
conda activate mambair
