class itk::GrayscaleFunctionErodeImageFilter< TInputImage, TOutputImage, TKernel >

gray scale function erosion of an image

Erode an image using functional grayscale morphology. Function erosion takes the minimum of all the pixels identified by the structuring element minus the structuring element value.

The structuring element can be composed of arbitrary nonnegative values (not restricted to zero or one). Element values greater than zero indicate pixels that will be considered during the dilation. The function erosion operation is defined as the minimum over the elements of the image value MINUS the structuring element value.

For the each input image pixel,

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