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. SkeletonTransformtreats values above t as foreground.
• 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.
