Detailed Description

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

geodesic gray scale dilation of an image

Geodesic dilation operates on a "marker" image and a "mask" image. The marker image is dilated using an elementary structuring element (neighborhood of radius one using only the face connected neighbors). The resulting image is then compared with the mask image. The output image is the pixelwise minimum of the dilated marker image and the mask image.

Geodesic dilation is run either one iteration or until convergence. In the convergence case, the filter is equivalent to "reconstruction by dilation". This filter is implemented to handle both scenarios. The one iteration case is multi-threaded. The convergence case is delegated to another instance of the same filter (but configured to run a single iteration).

The marker image must be less than or equal to the mask image (on a pixel by pixel basis).

Geodesic morphology is described in Chapter 6 of Pierre Soille's book "Morphological Image Analysis: Principles and Applications", Second Edition, Springer, 2003.
