Detailed Description

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

gray scale dilation of an image.

Dilate an image using grayscale morphology. Dilation takes the maximum 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 maximum value among the image neighbors where the kernel has elements > 0.
• Replace the original value with the max value
