Single Image Defogging Using a Fourth-Order Telegraph PDE Guided by Physical Haze Modeling
Manish Kumar, Rajendra K. Ray
In real-world scenarios, image defogging is an inverse problem due to unknown scene depth, atmospheric scattering, and the common absence of ground truth . To resolve the issue, we…

New Fourth-Order Grayscale Indicator-Based Telegraph Diffusion Model for Image Despeckling
Rajendra K. Ray, Manish Kumar
Second-order PDE models have been widely used for suppressing multiplicative noise, but they often introduce blocky artifacts in the early stages of denoising. To resolve this, we…
