Detailed Description

template<unsigned int VDimension>
class itk::FourierSeriesPath< VDimension >

Represent a closed path through ND Space by its frequency components.

This class is intended to represent closed parametric paths through an image which are defined by their Fourier coeficients (frequency components). The paths must be closed and defined over the interval [0,1], where the paths' values at input 0 and input 1 are identical. The user can control how many harmonics (how high of frequency components) are represented by a given instantiation of this class. Classic applications of this class include smoothing other closed paths (by finding and using only the first n harmonics of their frequency components) and interpolating exact derivatives of other closed paths by first converting the other paths to FourierSeriesPaths, which have an exactly defined algebraic derivative. (As many harmonics as are necessary to adequately approximate the original path should be used when approximating derivatives.)

void itk::FourierSeriesPath< VDimension >::AddHarmonic ( const VectorType CosCoefficients,

Clear all frequency coefficients (including the "DC" coefficients).

template<unsigned int VDimension>
virtual::itk::LightObject::Pointer itk::FourierSeriesPath< VDimension >::CreateAnother ( ) const
virtual

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::Object.

template<unsigned int VDimension>
virtual OutputType itk::FourierSeriesPath< VDimension >::Evaluate ( const InputType input) const
overridevirtual

Return the location of the parametric path at the specified location.

template<unsigned int VDimension>
virtual VectorType itk::FourierSeriesPath< VDimension >::EvaluateDerivative ( const InputType input) const
overridevirtual

Evaluate the first derivative of the ND output with respect to the 1D input. This is an exact, algebraic function.

template<unsigned int VDimension>
virtual const char* itk::FourierSeriesPath< VDimension >::GetNameOfClass ( ) const

template<unsigned int VDimension>
void itk::FourierSeriesPath< VDimension >::PrintSelf ( std::ostream &  os,
Indent  indent

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::Path< double, ContinuousIndex< SpacePrecisionType, VDimension >, VDimension >.
