Inheritance diagram for itk::PCAShapeSignedDistanceFunction< TCoordRep, VSpaceDimension, TImage >:


This class computes the signed distance from a N-dimensional shape defined by: (1) a mean signed distance image
, (2) the first
principal components images
and (3) a transform
to define the pose (i.e. position or orientation of the shape).
A particular instance of the shape is defined by a set of parameters
. The first
parameters defines the weights applied to each principal components and the remaining parameters is used to define the transform. The user should refer to the documentation of the particular Transform class being used. The first set of parameters are called the ShapeParameters and the remaining parameters the PoseParameters.
The method Evaluate( point x ) returns the approximate signed to the shape at point x such that:
Where [i] are the square root of the eigenvalues. These are defined using method SetPrincipalComponentStandardDeviations().
This class is templated over the coordinate representation type (e.g. float or double) and the space dimension.

This method is called when itkExceptionMacro executes. It allows the debugger to break on error. |
|
|
Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class. Reimplemented from itk::LightObject. |

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting. |

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used. |
