## Abstract Anisotropic diffusion filtering is widely used for MR image enhancement. However, the anisotropic filter is nonoptimal for MR images with spatially varying noise levels, such as images reconstructed from sensitivityβencoded data and intensity inhomogeneityβcorrected images. In this work
