Detailed Description

template<class TFixedImage, class TMovingSpatialObject>
class itk::ImageToSpatialObjectMetric< TFixedImage, TMovingSpatialObject >

Computes similarity between a moving spatial obejct and an Image to be registered.

The ImageToSpatialObjectMetric is different from the rest of the registration framework in ITK regarding the interpretation of the Transform with respect to the Fixed and Moving objects. In most of the ITK registration framework, the Transform computed by the optimizer is the one that maps points from the space of the Fixed object into the space of the Moving object. This direction of the transform is the one that makes easier to resample the Moving object into the space of the Fixed object.

In the particular case of the ImageToSpatialObject registration, the Transform to be computed is the one mapping points from the SpatialObject into the Image, despite the fact that the SpatialObject is called the "Moving" object and the image is called the "Fixed" object. This change of reference system is the consequence of using this type of registration in applications that are based on Visualization. In the context of such visualizations it is simpler to think in terms of the Transform that can be used for displaying the SpatialObject in the appropriate position with respect to the image. Since this process does not involve resampling, but providing a Transform to a visualization routine, it is usually more natural to use the Transform that maps points from the SpatialObject space the image space.

A full discussion of the Transform directions in the ITK registration framework can be found in the ITK Software Guide.
