Fig. 8From: Global denoising for 3D MRI Comparison of the denoising performance of the exact and approximated filter for BrainWeb T1w, T2w, PDw phantom, and real MRI and DWI datasets. Note that the dataset is corrupted with 20 % Rician noise, the sampling rate is computed as p = n/100, and PSNR is normalized by the results of the exact filterBack to article page
