Detail of filtering results. (a) Noisy T1 image. (b) MPVM filter result. (c) OMNLM-PCA filter result. (d) MGGM filter result. (e) Noise Free T1 image. (f) MPVM residuals. (g) OMNLM-PCA residuals. (h) MGGM residuals. As can be noticed, almost no anatomical information is visible in the image residuals for the compared methods (except for MPVM). However, with the proposed method, the image details are better preserved than the others.
