PGL-Net: Efficient Real-World Dehazing via Physics-Inspired Global-Local Decoupling
Welcome to the official model repository for PGL-Net. This repository hosts the pre-trained weights and highly optimized deployment files for our efficient real-world image dehazing network.
📝 Project Overview
PGL-Net (Physics-Inspired Global-Local Decoupling Network) is a lightweight architecture that embeds physical inductive biases via operator-level emulation to address the challenging ill-posed problem of single image dehazing.
Unlike traditional methods that suffer from inaccurate parameter estimation or deep learning approaches that act as heavy "black boxes," PGL-Net explicitly decouples the dehazing process into two stages:
- Global Distribution Rectification: The Physics-Inspired Affine Fusion (PAF) module implicitly models transmission and airlight subtraction to rectify feature distributions globally.
- Local Structural Refinement: The Degradation-Aware Modulation (DAM) block adaptively restores locally variant details.
As a result, PGL-Net achieves superior restoration quality comparable to heavy Transformer models, but with only ~3% of the parameters.
