📖 Introduction
We provide Kolors-Inpainting inference code and weights which were initialized with Kolors-Basemodel. Examples of Kolors-Inpainting results are as follows:
Model details
- For inpainting, the UNet has 5 additional input channels (4 for the encoded masked image and 1 for the mask itself). The weights for the encoded masked-image channels were initialized from the non-inpainting checkpoint, while the weights for the mask channel were zero-initialized.
- To improve the robustness of the inpainting model, we adopt a more diverse strategy for generating masks, including random masks, subject segmentation masks, rectangular masks, and masks based on dilation operations.
📊 Evaluation
For evaluation, we created a test set comprising 200 masked images and text prompts. We invited several image experts to provide unbiased ratings for the generated results of different models. The experts assessed the generated images based on four criteria: visual appeal, text faithfulness, inpainting artifacts, and overall satisfaction. Inpainting artifacts measure the perceptual boundaries in the inpainting results, while the other criteria adhere to the evaluation standards of the BaseModel. The specific results are summarized in the table below, where Kolors-Inpainting achieved the highest overall satisfaction score.
| Model | Average Overall Satisfaction | Average Inpainting Artifacts | Average Visual Appeal | Average Text Faithfulness |
|---|---|---|---|---|
| SDXL-Inpainting | 2.573 | 1.205 | 3.000 | 4.299 |
| Kolors-Inpainting | 3.493 | 0.204 | 3.855 | 4.346 |
The higher the scores for Average Overall Satisfaction, Average Visual Appeal, and Average Text Faithfulness, the better. Conversely, the lower the score for Average Inpainting Artifacts, the better.
The comparison results of SDXL-Inpainting and Kolors-Inpainting are as follows:
Kolors-Inpainting employs Chinese prompts, while SDXL-Inpainting uses English prompts.
