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
treats values above t as foreground.
MORE INFORMATION
  • SkeletonTransform gives an Image object in which the value of each nonzero pixel is the absolute Euclidean distance in pixels to the nearest pixel of background.
  • SkeletonTransform effectively gives the medial axis of foreground objects multiplied with the distance transform.
  • For multichannel images, SkeletonTransform operates on the intensity averaged over all channels.
  • A reduced medial axis can be obtained by setting True.
