Real-World Image Dehazing

What is it about?

Images taken in foggy or hazy weather often look blurry and unclear because tiny water particles in the air scatter light. Many computer programs can remove haze from synthetic, computer-generated images, but they often fail on real photos because real-world haze is much more complex. Our research develops a new method called Multilevel Subspace Distribution Adapter (MSDA) that helps the model better understand and adapt to real hazy conditions. We also design a Dual-Domain Synchronous Optimization (DDSO) strategy to train the system on both artificial and real images at the same time, improving its ability to restore clear details. As a result, our approach produces sharper, more natural-looking images and performs better on standard image quality tests without needing clear reference photos.

Why is it important?

Hazy images affect visibility and perception in photography, remote sensing, and autonomous driving. However, most learning-based dehazing models fail to generalize to real-world scenes. Our work is important because it bridges this gap by introducing an adaptive framework that learns from both synthetic and real data simultaneously. This makes the model more robust, interpretable, and reliable for practical outdoor vision tasks. By improving the clarity of real hazy images, it contributes to safer navigation, better environmental monitoring, and enhanced visual understanding in everyday applications.
