abstract = {<p style="text-align: justify;">An efficient feature-preserving fractional image denoising algorithm based
on a nonlinear spatial-fractional anisotropic diffusion equation is proposed. Two-sided
Grünwald-Letnikov fractional derivatives used in the PDE model are suitable to depict
the local self-similarity of images. The short memory principle is employed to simplify
the approximation scheme. Experimental results show that the method has an extremely
high structural retention property and keeps a remarkable balance between noise removal and feature preserving.</p>},
