Detailed Description

template<class TPixel, unsigned int VDimension = 2, class TAllocator = NeighborhoodAllocator<TPixel>>
class itk::BinaryBallStructuringElement< TPixel, VDimension, TAllocator >

A Neighborhood that represents a ball structuring element (ellipsoid) with binary elements.

This class defines a Neighborhood whose elements are either 0 or 1 depending on whether they are outside or inside an ellipsoid whose radii match the radii of the Neighborhood. This class can be used as a structuring element for the Morphology image filters.

A BinaryBallStructuringElement has an N-dimensional radius. The radius is defined separately for each dimension as the number of pixels that the neighborhood extends outward from the center pixel. For example, a 2D BinaryBallStructuringElement object with a radius of 2x3 has sides of length 5x7.

BinaryBallStructuringElement objects always have an unambiguous center because their side lengths are always odd.
