On a nonlinear evolution equation with spatially variable growth arising in multi-frame image super-resolution modeling

We study a nonlinear evolution equation with spatially variable growth arising from a regularized diffusion model for image restoration. The proposed model features a variable-exponent diffusion operator, allowing adaptive control of the diffusion intensity across the image domain, which enables effective noise suppres...

Existence, Uniqueness, and Numerical Experiments for a Caputo Fractional PDE With Variable‐Exponent Diffusion in Image Denoising

ABSTRACT We propose a novel nonlinear evolution model that integrates a Caputo time‐fractional derivative with a variable exponent diffusion operator for image decomposition and noise removal. The Caputo derivative captures memory effects through a fractional order, while the spatially adaptive exponent allows the diff...
