# MirrorPPR: Exemplar-Based Portrait Photo Retouching

This Space demonstrates [MirrorPPR](https://arxiv.org/abs/2606.29308), a novel framework for
exemplar-based portrait photo retouching. Given an exemplar pair (an original face image and its
retouched version), the model infers the retouching operations and applies them to a new query image.

## Usage

1. Upload a query face image you want to retouch.
2. Provide an exemplar pair: the original and retouched version of another face showing the desired
   retouching style. You can quickly load a pre-packaged exemplar pair from the template gallery.
3. Click "Retouch" to apply the exemplar's retouching operations to your query image.

## Model

This Space uses the [SJTU-DENG-Lab/MirrorPPR-Face](https://huggingface.co/SJTU-DENG-Lab/MirrorPPR-Face)
model, built on top of Qwen-Image-Edit with a Retouching Operation Extractor (MAE + R-Former + Connector)
and LoRA adaptation.
