Updates

This project is under active development, please stay tuned! ☕

Sep 29, 2024: Code & models of ProRes are released, and some minor issues have been fixed. We will update the arXiv version with more details upon acceptance.

Aug 28, 2024: Our newest paper Perceive-IR is on arXiv and under peer review! Perceive-IR performs well under two all-in-one settings.

Jun 26, 2023: We've released ProRes! We wish this work would inspire more works on prompt learning with image restoration tasks. Code & models are coming soon!

Highlights

• ProRes addresses universal image restoration with degradation-aware prompts, which is the first prompt-based versatile framework for image restoration.

• ProRes demonstrate two superior capabilities: (1) control ability for desired outputs and (2) transferability based on prompt tuning.

• ProRes can be easily adapted for new tasks or new datasets through effective and efficient prompt tuning.

• Specific prompts can control the output of ProRes. Moreover, combining different prompts can tackle the images with multiple corruptions.

Visualizations

Control Ability

1.Independent Control

Visualization results processed from images of different corruptions. Compared with the original inputs, the outputs are consistent with the given visual prompts.

2. Sensitive to Irrelevant Task-specific Prompts

Visualization results processed by different prompts. Compared with the original inputs, the outputs remain unchanged with irrelevant visual prompts.

3. Tackle Complicated Corruptions

Visualization results processed by ProRes from images of mixed types of degradation, i.e., low-light and rainy. ProRes adopts two visual prompts for low-light enhancement (E) and deraining (D) and combines the two visual prompts by linear weighted sum, i.e., αD + (1 − α)E, to control the restoration process.

Adaptation on New Datasets & Task

1. Low-light Enhancement Results

Visualization results of ProRes on the FiveK dataset. We adopt two settings, i.e., direct inference and prompt tuning, to evaluate ProRes on the FiveK dataset (a new dataset for low-light enhancement).

2. Dehazing Results

Visualization results of ProRes on the RESIDE-6K dataset via prompt tuning for image dehazing (a new task).
