Methods | Parameters | Default | Sampling | Effects of larger value |
---|---|---|---|---|
BET | -f (fractional intensity threshold) | 0.5 | 0.1:0.05:0.8 | Smaller brain outline |
-g (vertical gradient) | 0 | −0.3:0.1:0.2 | Larger brain outline at bottom | |
BSE | -d (diffusion constant) | 25 | 5:5:35 | Blur across larger intensity differences |
-s (edge detection constant) | 0.62 | 0.5:0.05:0.8 | Detect only wider edges | |
-r (erosion size) | 1 | 1, 2 | Break wider connections |
