Detailed Description

template<class TImageType, class TCoordRep = float>
class itk::BSplineResampleImageFunction< TImageType, TCoordRep >

Resample image intensity from a BSpline coefficient image.

This class resample the image intensity at a non-integer position from the input BSpline coefficient image.

Spline order may be from 0 to 5.

In ITK, BSpline coefficient can be generated using a BSplineDecompositionImageFilter. Using this image function in conjunction with ResampleImageFunction allows the reconstruction of the original image at different resolution and size.

unsigned long itk::Object::AddObserver ( const EventObject &  event,

unsigned long itk::Object::AddObserver ( const EventObject &  event,
Command *   
) [inherited]

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

) const [protected, virtual, inherited]

The following methods take working space (evaluateIndex, weights, weightsDerivative) that is managed by the caller. If threadID is known, the working variables are looked up in the thread indexed arrays. If threadID is not known, working variables are made on the stack and passed to these methods. The stack allocation should be ok since these methods do not store the working variables, i.e. they are not expected to be available beyond the scope of the function call.

This was done to allow for two types of re-entrancy. The first is when a threaded filter, e.g. InterpolateImagePointsFilter calls EvaluateAtCon
