After InstantIR processing, drag the `Restoration Previews` slider to explore other in-progress versions; 2. If you like one of them, set the `Start Free Rendering` slider to the same value to get a more refined result. ### Creative restoration: 1. Check the `Creative Restoration` checkbox; 2. Input your text prompts in the `Restoration prompts` textbox; 3. Set `Start Free Rendering` slider to a medium value (around half of the `steps`) to provide adequate room for InstantIR creation. ## Examples Here are some examplar usage of InstantIR: """) # examples = gr.Gallery(label="Examples") gr.Markdown( """ ## Citation If InstantIR is helpful to your work, please cite our paper via: ``` @article{huang2024instantir, title={InstantIR: Blind Image Restoration with Instant Generative Reference}, author={Huang, Jen-Yuan and Wang, Haofan and Wang, Qixun and Bai, Xu and Ai, Hao and Xing, Peng and Huang, Jen-Tse}, journal={arXiv preprint arXiv:2410.06551}, year={2024} } ``` """) demo.queue().launch()
