Detailed Description

template<class TInputImage, class TOutputImage = TInputImage>
class itk::ConstantBoundaryCondition< TInputImage, TOutputImage >

This boundary condition returns a constant value for out-of-bounds image pixels.

For example, invoking this function object with a constant value of zero (the default) on each out-of-bounds element of a 7x5 iterator that masks a region at an image corner (iterator is centered on the 2):

* * * * * * * * * * * * * * * * 1 2 3 4 5 (where * denotes pixels that lie * * 3 3 5 5 6 outside of the image boundary) * * 4 4 6 7 8

would produce the following neighborhood of values:

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 2 3 4 5 0 0 3 3 5 5 6 0 0 4 4 6 7 8

Note:: If you are using an image with Array as the pixel type, you will need to set the constant explicitly with an array of the appropriate length. This is also true if your image type is a VectorImage.

virtual RegionType itk::ConstantBoundaryCondition< TInputImage, TOutputImage >::GetInputRequestedRegion	(	const RegionType &	inputLargestPossibleRegion,
		const RegionType &	outputRequestedRegion
	)		const `[virtual]`

Determines the necessary input region for the output region. For this boundary condition, only the intersection of the largest possible image region and the output requested region is needed.

Parameters:

inputLargestPossibleRegion	Largest possible region of the input image.
outputRequestedRegion	The output requested region.

Returns:: The necessary input region required to determine the pixel values in the outputRequestedRegion.
