Detailed Description

template<class TImage>
class itk::PeriodicBoundaryCondition< TImage >

A function object that determines values outside of image boundaries according to periodic (wrap-around) conditions.

The input to this function object is a neighborhood iterator. This boundary condition object is designed to be given as a template argument to a NeighborhoodIterator or any of the NeighborhoodIterator subclasses.

virtual bool itk::ImageBoundaryCondition< TImage >::RequiresCompleteNeighborhood ( )

inlinevirtualinherited

Tell if the boundary condition can index to any location within the associated iterator's neighborhood or if it has some limited subset (such as none) that it relies upon. Subclasses should override this method if they can safely limit indexes to active pixels (or no pixels).

Reimplemented in itk::ConstantBoundaryCondition< TImage >.
