About

What is PMRF?

PMRF (Posterior-Mean Rectified Flow) is an open-source implementation of a novel photo-realistic image restoration algorithm, presented at ICLR 2025. It provably approximates the optimal estimator that minimizes the Mean Squared Error (MSE) while maintaining a perfect perceptual quality constraint. The tool provides capabilities for blind face image restoration and controlled experiments, offering model checkpoints and test datasets for evaluation. It supports various architectures, including HDiT and UNet, and includes installation instructions for setting up a conda environment. PMRF is ideal for researchers and developers focused on advancing image restoration techniques.

Best used for

Ideal for researchers and developers who need to implement and evaluate advanced image restoration algorithms, conduct quantitative and visual comparisons of restoration methods, and train novel image restoration models.

FAQs

What kind of image restoration tasks can PMRF handle?

PMRF is designed for photo-realistic image restoration, specifically excelling in blind face image restoration. It also supports controlled experiments for various degradation types, allowing for comprehensive evaluation of its performance against baseline methods in scenarios like denoising and colorization.

What are the system requirements for installing PMRF?

PMRF requires a Python 3.10 environment and specific versions of PyTorch, torchvision, and torchaudio, compatible with CUDA 11.8. Users may encounter issues with the `natten` package on Windows, for which alternative architectures like UNet or specific installation workarounds are suggested.

Does PMRF provide pre-trained models?

Yes, PMRF provides pre-trained model checkpoints for blind face image restoration, available on Hugging Face and Google Drive. Checkpoints for controlled experiments and necessary metrics evaluation files (like `resnet18_110.pth`) are also provided for download, ensuring quick setup for evaluation.
