摘要
To better preserve the edge features, this paper investigates an adaptive total variation regularization based variational model for removing Poisson noise. This edge-preserving scheme comprises a spatially adaptive diffusivity coefficient, which adjusts the diffusion strength automatically. Compared with the classical total variation based one, numerical simulations distinctly indicate the superiority of our proposed strategy in maintaining the small details while denoising Poissonian image.
