[Insight-users] Re: Marker controlled watershed, how to realize in ITK

[Josiah Yoder]

I just want to comment that the morphological reconstruction filters
are now available in ITK, as discussed in this ITK paper:

I believe the morphological reconstructions are related to the
geodesic morphology algorithms.  There are a number of geodesic
morphology algorithms in ITK

itkGrayscaleConnectedClosingImageFilter.h
itkGrayscaleConnectedOpeningImageFilter.h
itkGrayscaleFillholeImageFilter.h
itkGrayscaleGeodesicDilateImageFilter.h
itkGrayscaleGeodesicErodeImageFilter.h
itkGrayscaleGrindPeakImageFilter.h
itkHConcaveImageFilter.h
itkHConvexImageFilter.h
itkHMaximaImageFilter.h
itkHMinimaImageFilter.h

Also, I am wondering if itk implemented the "morphological
reconstruction" algorithm.  The following example mention about it.
http://www.mathworks.com/products/demos/image/watershed/ipexwatershed.html

There is also some papers like:

Luc Vincent, "Morphological Grayscale Reconstruction in Image
Analysis: Applications and Efficient Algorithms," IEEE transactions on
Image Processing, vol 2 no. 2 1993.
