Detailed Description

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

This class compute the signed (positive and negative) chamfer distance in a narrow band.

OVERVIEW

This filter computes a Signed Chamfer Distance Map of the input image specialy designed to work within the Level Set framework, in the Narrow Band Reinitialization (generally applied after IsoContourDistanceImageFilter ). It can however be used for other purposes.

The input is assumed to contain voxels with values higher than the Maximal Computed Distance, or values between -1 and 1 for voxels close to the 0-isosurface from which we compute the distance.

This filter is N-dimensional.
