MirrorPPR: Exemplar-Based Portrait Photo Retouching

This Space demonstrates MirrorPPR, 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 model, built on top of Qwen-Image-Edit with a Retouching Operation Extractor (MAE + R-Former + Connector) and LoRA adaptation.
