Class Thinning


public class Thinning extends Object
Implementation of the 3D binary thinning algorithm of
Lee et al.
"Building skeleton models via 3-D medial surface/axis thinning algorithms."
Computer Vision, Graphics, and Image Processing, 56(6):462–478, 1994.
This is a new implementation, developed with reference to the original paper and two other implementations:
  • the ITK version from Hanno Homann (possibly-broken link
  • the Skeletonize3D ImageJ plugin by Ignacio Arganda-Carreras
These were mostly used to help debug thorny issues around pixel ordering in the lookup tables. This implementation uses a different design with some additional optimizations, but should give the same results as "Skeletonize3D".

      public static void thin(Mat mat)
      Thin the binary image in Mat. Here, the image is assumed to be 2D or 3D; if 3D, then the z information is found along the channels dimension.

      The thinning is performed in-place. The image is converted to uint8 if required; non-zero pixels are considered foreground and zero pixels background.

      The resulting image has 0 in the background and retains the original (after conversion to 8-bit) value in the foreground (typically 1 or 255).
