Detailed Description

This calss performs the interpolation of two Spectrum processing data objects.

It Allows any possible attribute configuration in its inputs and in its output, but it performs faster when prototype configuration of the data is specified using SetPrototypes(...), in certain situations:

Todo:
Possible optimisations (which require more states):

The BPFxBPF sum is being thought. If both BPFs have the same range and point possition, the way to go is obvious, but in other situations it is not so simple. Whe should probably merge both BPFs, into a new BPF.

Member Function Documentation

bool CLAM::SpectrumInterpolator::Do ( void  )
virtual

Supervised mode execution method (using ports)

Returns:
A boolean telling whether it has been output

Implements CLAM::Processing.

Definition at line 106 of file SpectrumInterpolator.cxx.

References CLAM_ASSERT.

Referenced by CLAM::FrameInterpolator::Do(), and CLAM::SMSMorph::Do().

bool CLAM::SpectrumInterpolator::Do ( Spectrum in1,
Spectrum in2,
Spectrum out 
)
const ProcessingConfig& CLAM::SpectrumInterpolator::GetConfig ( ) const
inlinevirtual

Configuration getter.

Gets the configuration parameters used to create the object.

Returns:
Const reference to the configuration object. The usual way to perform a configuration change in the processing object is to take a copy of this reference, to change it and to send it with the Configure method. If not overriden, it returns a NullProcessingConfig.

Reimplemented from CLAM::Processing.

Definition at line 153 of file SpectrumInterpolator.hxx.

bool CLAM::SpectrumInterpolator::SetPrototypes ( const Spectrum in1,
const Spectrum in2,
const Spectrum out 
)

Change the internal type state.

Apart from prototype configuration, the Size, Scale and SpectralRange attributes of each Spectrum are also checked.
