SkeletonTransform

SkeletonTransform[image] gives the skeleton transform of image, in which the value of each skeleton pixel is its distance to the nearest background pixel.

• SkeletonTransform[image, t] treats values above t as foreground.

Examples

Compute the skeleton transform of an image:

img = Binarize[ExampleData[{"TestImage", "Blob"}]];
SkeletonTransform[img]

Apply with a custom threshold:

SkeletonTransform[ExampleData[{"TestImage", "Fingerprint"}], 0.5]
