Adaptive non-local means denoising of MR images with spatially varying noise levels

Purpose: To adapt the so‐called nonlocal means filter to deal with magnetic resonance (MR) images with spatially varying noise levels (for both Gaussian and Rician distributed noise). Materials and Methods: Most filtering techniques assume an equal noise distribution across the image. When this assu...
