Detailed Description

This is the mother class of image-based transformation class.

This class is a virtual one, in the sense that it cannot be used on its own because several pure virtual functions belong to it. Its children are implementations of actual deformation models.
Everywhere in the code, this parent class should be used instead of any of its children.
It can be used during the projection/reconstruction process by the oDeformationManager through the use of the Deformation functions that cannot be overloaded:

ApplyDeformationsToForwardImage() : Initial deformation of the forward image matrice
PerformDeformation() : Deformation of the forward image during the reconstruction process
ApplyDeformationsToBackwardImage() : Final deformation of the backward image
PerformSensitivityDeformation() : Forward or backward deformation during the sensitivity generation process
All children must implement the following pure virtual functions:
- ReadAndCheckConfigurationFile(): read specific options from a configuration file
- ReadAndCheckOptionsList(): read specific options from a string
- ShowHelp(): print helps about the deformation model specifications
- Initialize(): initialize specific stuff of the model (if required)
- CheckParameters(): Check the initialization of the parameters (if required)
- ApplyDeformations(): implement the actual deformation
