Description
Estimate the gyrification index at a specific scale. This will produce images of
local sulcification and gyrification as as well as the difference of these
two measurements. The most gyral values are near 1 and most sulcal negative 1.
The function is not limited to brain data and should work on any 3D shape.
See the paper entitled the shape operator for differential image analysis.
Usage
1
localGyrificationIndex(segmentation, sigma = 3, k = 25, ksigma = 3)
Arguments
segmentation
- potentially from antsCorticalThickness
sigma
- scale parameter
k
- size of neighborhood
ksigma
- sigma for k-neighborhood
Value
lGI image
