Brain MR image denoising for Rician noise using pre-smooth non-local means filter

BACKGROUND: Magnetic resonance imaging (MRI) is corrupted by Rician noise, which is image dependent and computed from both real and imaginary images. Rician noise makes image-based quantitative measurement difficult. The non-local means (NLM) filter has been proven to be effective against additive n...
