Detailed Description

template<class TInputImage, class TOutputImage>
class itk::BinaryThinningImageFilter3D< TInputImage, TOutputImage >

This filter computes one-pixel-wide skeleton of a 3D input image.

This class is parametrized over the type of the input image and the type of the output image.

The input is assumed to be a binary image. All non-zero valued voxels are set to 1 internally to simplify the computation. The filter will produce a skeleton of the object. The output background values are 0, and the foreground values are 1.

A 26-neighbourhood configuration is used for the foreground and a 6-neighbourhood configuration for the background. Thinning is performed symmetrically in order to guarantee that the skeleton lies medial within the object.

This filter is a parallel thinning algorithm and is an implementation of the algorithm described in:

T.C. Lee, R.L. Kashyap, and C.N. Chu. Building skeleton models via 3-D medial surface/axis thinning algorithms. Computer Vision, Graphics, and Image Processing, 56(6):462–478, 1994.

To do: Make use of multi-threading.
