High-Quality Image Restoration Following Human Instructions
Authors: name: Marcos V. Conde, name: Gregor Geigle, name: Radu Timofte

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. Our code, datasets and models
