Detailed Description

class itk::GrayscaleGeodesicErodeImageFilter< TInputImage, TOutputImage >

geodesic gray scale erosion of an image

Geodesic erosion operates on a "marker" image and a "mask" image. The marker image is eroded 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 maximum of the eroded marker image and the mask image.

Geodesic erosion is run either one iteration or until convergence. In the convergence case, the filter is equivalent to "reconstruction by erosion". 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 greater 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.

A noniterative version of this algorithm can be found in the ReconstructionByErosionImageFilter. This noniterative solution is much faster than the implementation provided here. All ITK filters that previously used GrayscaleGeodesicErodeImageFilter as part of their implementation have been converted to use the ReconstructionByErosionImageFilter. The GrayscaleGeodesicErodeImageFilter is maintained for backward compatibility.
