Abstract
Single-image dehazing is vital for restoring clear visuals from haze-affected images in applications like surveillance and autonomous driving. Most existing models struggle with local haze variations and detail preservation in dense haze. This study introduces HazeTrendNet, a lightweight dehazing framework, incorporating haze-concentration-trend guidance via transmittance estimation, dynamic convolution kernel selection and haze-aware attention. Experiments show state-of-the-art performance: PSNR/SSIM of 42.29 dB/0.997 on RESIDE-Indoor, 17.68 dB/0.655 on Dense-Haze and 22.14 dB/0.812 on NH-HAZE, outperforming EENet, SANet and FocalNet. With 6.17 M parameters and 56.46 GFLOPs, it suits edge deployment.
