🔎Quality Map

Perceptual Quality Map

python PQ-Map.py -p /orignal/image/path

Change draw to enable a quality map output. multi for using onr/multiple embedings. (Condisering overall quality, or quality in different aspect)

Alignment Quality Map

python AQ-Map.py -p /orignal/image/path -q "your prompt"

Change draw to enable a quality map output.

🚀 Full Refining Pipeline

Q-Refine

G-Refine

For the backbone of refining steps 1 and 2. First, please ensure you have the SDXL-Inpainting model. Then run https://github.com/yangxy/PASD.git to install PASD in this dictionary.

Then please use refine.ipynb to refine the alignment-example.png image. You may also use your own image and its corresponding prompt.

🌈Training

📌 TODO

• ✅ Release the PQ-Map code (Q-Refine and G-Refine)
• ✅ Release the AQ-Map code (G-Refine only)
• Release the Q-Refine code
• ✅ Release the G-Refine code
• Release the training script
