Hi John
you can try mri_nlfilter if you like. It implement a nonlocal means/medians
algorithm that I wrote in 1995 or so:
Bruce Fischl and Eric L. Schwartz.
1999. Adaptive Nonlocal Filtering: A Fast Alternative to Anisotropic
Diffusion for Image Enhancement. IEEE Trans. Pattern Anal. Mach. Intell.
21, 1 (January 1999), 42-48. DOI=http://dx.doi.org/10.1109/34.745732
I'm not sure I would trust thickness estimates after nonlinear filtering,
but it might help getting surface reconstructions and parcellations and
such.
cheers
Bruce

Hi FS experts,
I have T1 images with low quality (noise and artifacts). I am wondering if
smoothing these images, before runing the command "Recon-all", can help to
improve the segmentation and parcellation process for these images.
Thanks for any advice!
Bests,
John
