Nonlocal-to-local convergence of the -Biharmonic evolution equation with the Dirichlet boundary condition
Kehan Shi, Yi Ran
This paper studies the nonlocal -biharmonic evolution equation with the Dirichlet boundary condition that arises in image processing and data analysis. We prove the existence an…

Coupling local and nonlocal total variation flow for image despeckling
Yi Ran, Zhichang Guo, Kehan Shi +4
Nonlocal equations effectively preserve textures but exhibit weak regularization effects in image denoising, whereas local equations offer strong denoising capabilities yet fail to…
