Detailed Description

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

gray scale dilation of an image.

Erode an image using grayscale morphology. Erosion takes the minimum of all the pixels identified by the structuring element.

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.

For the each input image pixel,

• NeighborhoodIterator gives neighbors of the pixel.
• Evaluate() member function returns the minimum value among the image neighbors where the kernel has elements > 0
• Replace the original value with the min value

Member Function Documentation

template<class TInputImage, class TOutputImage, class TKernel> virtual PixelType itk::GrayscaleErodeImageFilter< TInputImage, TOutputImage, TKernel >::Evaluate (  const NeighborhoodIteratorType &    nit, const KernelType &    kernel )  [protected, virtual]

Evaluate image neighborhood with kernel to find the new value for the center pixel value. It will return the minimum value of the image pixels whose corresponding element in the structuring element is positive. This version of Evaluate is used for non-boundary pixels. Implements itk::MorphologyImageFilter< TInputImage, TOutputImage, TKernel >.

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

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

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

Standard New method. Reimplemented from itk::Object.
