9.9. ITK Binary Erode Image Filter
Fast binary erosion of a single intensity value in the image.

ITKBinaryMathematicalMorphology (BinaryMathematicalMorphology)
Description
BinaryErodeImageFilter is a binary erosion morphologic operation on the foreground of an image. Only the value designated by the intensity value “SetForegroundValue()” (alias as SetErodeValue() ) is considered as foreground, and other intensity values are considered background.
Grayscale images can be processed as binary images by selecting a “ForegroundValue” (alias “ErodeValue”). Pixel values matching the erode value are considered the “foreground” and all other pixels are “background”. This is useful in processing segmented images where all pixels in segment #1 have value 1 and pixels in segment #2 have value 2, etc. A particular “segment number” can be processed. ForegroundValue defaults to the maximum possible value of the PixelType. The eroded pixels will receive the BackgroundValue (defaults to NumericTraits::NonpositiveMin() ).
The structuring element is assumed to be composed of binary values (zero or one). Only elements of the structuring element having values > 0 are candidates for affecting the center pixel. A reasonable choice of structuring element is itk::BinaryBallStructuringElement .
This implementation is based on the papers:
L.Vincent “Morphological transformations of binary images with arbitrary structuring elements”, and
N.Nikopoulos et al. “An efficient algorithm for 3d binary morphological transformations with 3d structuring elements for arbitrary size and shape”. IEEE Transactions on Image Processing. Vol. 9. No. 3. 2000. pp. 283-286.* ImageToImageFilter BinaryDilateImageFilter BinaryMorphologyImageFilter
