Detailed Description

template<typename TFixedImage, typename TMovingSpatialObject>
class itk::ImageToSpatialObjectRegistrationMethod< TFixedImage, TMovingSpatialObject >

Base class for Image Registration Methods.

This class is templated over the type of the image and the type of the SpatialObject to be registered. A generic Transform is used by this class. That allows to select at run time the particular type of transformation that is to be applied for registering the images.

This method use a generic Metric in order to compare the two images. the final goal of the registration method is to find the set of parameters of the Transformation that optimizes the metric.

The registration method also support a generic optimizer that can be selected at run-time. The only restriction for the optimizer is that it should be able to operate in single-valued cost functions given that the metrics used to compare images provide a single value as output.

The terms : Fixed image and Moving SpatialObject are used in this class to indicate that the SpatialObject is being mapped by the transform.

This class uses the coordinate system of the Fixed image and searchs for a transform that will map the Moving SpatialObject on top of the Fixed image. For doing so, a Metric will be continuously applied to compare the Fixed image with the Transformed Moving SpatialObject.

The ImageToSpatialObjectRegistrationMethod 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.
