Detailed Description

template<class TInputChainCodePath, class TOutputFourierSeriesPath>
class itk::ChainCodeToFourierSeriesPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >

Filter that produces a Fourier series version of a chain code path.

ChainCodeToFourierSeriesPathFilter produces a Fourier series representation of a chain code path. By default, the first 8 harmonics (frequency coefficients, which include the "DC" term) are computed. SetNumberOfHarmonics() can be used to override this value. Because the requested number of harmonics may not be able to be computed, it is advisable to check the number of harmonics in the actual output.

Member Function Documentation

template<class TInputChainCodePath, class TOutputFourierSeriesPath> void itk::ChainCodeToFourierSeriesPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >::GenerateData (  void   )  [protected, virtual]

This method causes the filter to generate its output. Reimplemented from itk::ProcessObject.

template<class TInputChainCodePath, class TOutputFourierSeriesPath> virtual const char* itk::ChainCodeToFourierSeriesPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >::GetClassName (   )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::PathToPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >.

template<class TInputChainCodePath, class TOutputFourierSeriesPath> Pointer itk::ChainCodeToFourierSeriesPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >::New (   )  [static]

Method for creation through the object factory. Reimplemented from itk::PathToPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >.

template<class TInputChainCodePath, class TOutputFourierSeriesPath> void itk::ChainCodeToFourierSeriesPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >::PrintSelf (  std::ostream &  os, Indent  indent )  const [protected, virtual]

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::PathToPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >.

template<class TInputChainCodePath, class TOutputFourierSeriesPath> virtual void itk::ChainCodeToFourierSeriesPathFilter< TInputChainCodePath, TOutputFourierSeriesPath >::SetNumberOfHarmonics (  unsigned int  _arg  )  [virtual]

Set the number of harmonics to try to compute. By default, the first 8 harmonics (frequency coefficients, which include the "DC" term) are computed. SetNumberOfHarmonics() can be used to override this value. If the chain code has too few steps to calculate the desired number of harmonics (due to the Nyquist criterion), then as many harmonics as are possible (input->NumberOfSteps()/2) will be calculated, but at least 2 harmonics will always be calculated.
