Re: [Freesurfer] smoothing T1 images

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.

[Freesurfer] smoothing T1 images

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
