Detailed Description

template<class TInputImage, class TOutputImage, class TKernel>
class itk::ErodeObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >

Erosion of an object in an image.

Erosion of an image using binary morphology. Pixel values matching the object value are considered the "object" and all other pixels are "background". This is useful in processing mask images containing only one object.

If the pixel covered by the center of the kernel has the pixel value ObjectValue and the pixel is adjacent to a non-object valued pixel, then the kernel is centered on the object-value pixel and neighboring pixels covered by the kernel are assigned the background value. The structuring element is assumed to be composed of binary values (zero or one).

Member Function Documentation

template<class TInputImage, class TOutputImage, class TKernel> void itk::ErodeObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >::Evaluate (  OutputNeighborhoodIteratorType &  nit, const KernelType &  kernel )  [protected, virtual]

Apply the kernel to the neighborhood given. All values in neighborhood covered by the kernel will be set to the background value. Implements itk::ObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >.

template<class TInputImage, class TOutputImage, class TKernel> virtual PixelType itk::ErodeObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >::GetBackgroundValue (   )  [virtual]

Get the value to be assigned to eroded pixels

template<class TInputImage, class TOutputImage, class TKernel> virtual const char* itk::ErodeObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >::GetClassName (   )  const [virtual]

Runtime information support Reimplemented from itk::ObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >.

template<class TInputImage, class TOutputImage, class TKernel> Pointer itk::ErodeObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >::New (   )  [static]

Standard New method Reimplemented from itk::Object.

template<class TInputImage, class TOutputImage, class TKernel> void itk::ErodeObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >::PrintSelf (  std::ostream &  os, Indent  indent )  const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from itk::ObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >.

template<class TInputImage, class TOutputImage, class TKernel> virtual void itk::ErodeObjectMorphologyImageFilter< TInputImage, TOutputImage, TKernel >::SetBackgroundValue (  PixelType  _arg  )  [virtual]

Set the value to be assigned to eroded pixels
