finds the skeletons of foreground regions in image by applying morphological thinning until convergence.


performs n iterations of morphological thinning.


treats values above t as foreground.

Details and Options

  • Thinning[image,] yields a binary image in which pixels representing the morphological skeleton have value 1 and others have value 0.
  • Thinning[image] is equivalent to Thinning[image,Infinity].
  • Thinning works with binary, grayscale, and arbitrary multichannel images, as well as real matrices.
  • Thinning takes a Padding option that specifies the values to assume for pixels outside the image. The default setting is Padding->0.
  • Thinning supports a Method option which specifies what thinning algorithm to be used. Possible settings include:
  • "Morphological"morphological thinning (default)
    "MedialAxis"approximate medial axis
