Skeletonize a binary segmentation. — skeletonize • ANTsR

Employ a topologically constrained label propagation tool in order to thin an existing segmentation into a skeleton. The function will perform better if the initial segmentation is well-composed.

skeletonize(x, laplacianThreshold = 0.25, propagationOption = 1)

Arguments

x	input binary image
laplacianThreshold	between zero and one, controls the speed image
propagationOption	either 0 (none), 1 (well-composed) or 2 (topological) constraint

Value

output binary image

Examples


img = antsImageRead( getANTsRData( 'r16') ) %>% thresholdImage( "Otsu", 3 )
skel = skeletonize( thresholdImage( img, 3, 3 ) )
