Researchers have developed a new fourth-order coupled hyperbolic-parabolic partial differential equation (PDE) model for image despeckling. This advanced model aims to reduce speckle noise in images from systems like SAR and ultrasound while better preserving fine details and structural features compared to traditional second-order methods. The framework utilizes adaptive diffusion coefficients and an edge indicator function, with a finite-difference scheme for implementation, demonstrating superior performance in experiments. AI
