MMSR is an open source image and video super-resolution toolbox based on PyTorch. It is a part of the [open-mmlab](https://github.com/open-mmlab) project developed by [Multimedia Laboratory, CUHK](http://mmlab.ie.cuhk.edu.hk). MMSR is based on our previous projects: [BasicSR](https://github.com/xinntao/BasicSR), [ESRGAN](https://github.com/xinntao/ESRGAN), and [EDVR](https://github.com/xinntao/EDVR).
- **A unified framework** suitable for image and video super-resolution tasks. It is also easy to adapt to other restoration tasks, e.g., deblurring, denoising, etc.
- **State of the art**: It includes several winning methods in competitions: such as ESRGAN (PIRM18), EDVR (NTIRE19).
- **Easy to extend**: It is easy to try new research ideas based on the code base.
- [Deformable Convolution](https://arxiv.org/abs/1703.06211). We use [mmdetection](https://github.com/open-mmlab/mmdetection)'s dcn implementation. Please first compile it.
We use datasets in LDMB format for faster IO speed. Please refer to [DATASETS.md](datasets/DATASETS.md) for more details.
## Training and Testing
Please see [wiki- Training and Testing](https://github.com/open-mmlab/mmsr/wiki/Training-and-Testing) for the basic usage, *i.e.,* training and testing.
## Model Zoo and Baselines
Results and pre-trained models are available in the [wiki-Model Zoo](https://github.com/open-mmlab/mmsr/wiki/Model-Zoo).
## Contributing
We appreciate all contributions. Please refer to [mmdetection](https://github.com/open-mmlab/mmdetection/blob/master/CONTRIBUTING.md) for contributing guideline.
We adopt [PEP8](https://python.org/dev/peps/pep-0008) as the preferred code style. We use [flake8](http://flake8.pycqa.org/en/latest) as the linter and [yapf](https://github.com/google/yapf) as the formatter. Please upgrade to the latest yapf (>=0.27.0) and refer to the [yapf configuration](.style.yapf) and [flake8 configuration](.flake8).
