Smoothing gone bad Solution: Increase Niter 7/2/2004 SSCC/NIMH 72
Smoothing geometry of surface • Surface geometry smoothing can also be done with SurfSmooth The difficulty in geometry smoothing is in preventing the surface from shrinking in size. SurfSmooth uses the smoothing algorithm by (Taubin G. 2000) • Demo (close SUMA and AFNI) Execute: source run_SurfSmooth_geom The script will add noise to the smoothwm surface, then filter it SUMA is then launched and the script waits for you to setup Turn off background colors (‘b’) Switch to noisy surface (‘.’) Turn recorder ON Hit enter twice (in the shell) to launch the smoothing program Watch the smoothing progress with each iteration. You can play the whole sequence at the end. 7/2/2004 SSCC/NIMH 73
