Thinning

Thinning[image]
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.

Thinning yields a binary image in which pixels representing the morphological skeleton have value 1 and others have value 0.

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.

Thinning supports a Method option which specifies what thinning algorithm to be used. Possible settings include:

	"Morphological"	morphological thinning (default)
	"MedialAxis"	approximate medial axis
