Researchers propose novel PDE-based defogging method for clearer images

Researchers have developed a novel single-image defogging method that combines a fourth-order nonlinear partial differential equation (PDE) with a physical haze model. This approach utilizes the Dark Channel Prior to estimate atmospheric parameters and generate a guidance image, with the final restoration achieved through a fourth-order PDE evolution. The method incorporates an edge-adaptive diffusion coefficient and a fidelity term weighted by the transmission map, which effectively reduces haze while preserving image details. AI
