itk::RectangularImageNeighborhoodShape< VImageDimension > Class Template Reference

#include <itkRectangularImageNeighborhoodShape.h>

Detailed Description

template<unsigned int VImageDimension>
class itk::RectangularImageNeighborhoodShape< VImageDimension >

Rectangular (or hyperrectangular) image-neighborhood shape. Eases creating a sequence of offsets for ShapedImageNeighborhoodRange. Can also be used for ShapedNeighborhoodIterator.

The following example creates a 3 x 5 rectangular neighborhood around pixel location [10, 20], and generates the offsets for a neighborhood range:

const Index<> location = { 10, 20 };
const Size<> radius = { { 1, 2 } };
const RectangularImageNeighborhoodShape<2> shape{ radius };
const std::vector<Offset<>> offsets = GenerateImageNeighborhoodOffsets(shape);
ShapedImageNeighborhoodRange<ImageType> neighborhoodRange{ *image, location, offsets };
