Abstract (click me to read)

Image restoration is a fundamental problem that involves recovering a high-quality clean image from its degraded observation. All-In-One image restoration models can effectively restore images from various types and levels of degradation using degradation-specific information as prompts to guide the restoration model. In this work, we present the first approach that uses human-written instructions to guide the image restoration model. Given natural language prompts, our model can recover high-quality images from their degraded counterparts, considering multiple degradation types. Our method, InstructIR, achieves state-of-the-art results on several restoration tasks including image denoising, deraining, deblurring, dehazing, and (low-light) image enhancement. InstructIR improves +1dB over previous all-in-one restoration methods. Moreover, our dataset and results represent a novel benchmark for new research on text-guided image restoration and enhancement.

> **Disclaimer:** please remember this is not a product, thus, you will notice some limitations. **This demo expects an image with some degradations (blur, noise, rain, low-light, haze) and a prompt requesting what should be done.** Due to the GPU memory limitations, the app might crash if you feed a high-resolution image (2K, 4K).
The model was trained using mostly synthetic data, thus it might not work great on real-world complex images. However, it works surprisingly well on real-world foggy and low-light images. You can also try general image enhancement prompts (e.g., "retouch this image", "enhance the colors") and see how it improves the colors.
