Detailed Description

template<class NUMTYPE = float>
class gcgBASIS1D< NUMTYPE >

Abstract class for 1D basis projection/reconstruction interfaces.

Template Parameters

NUMTYPE Type of the samples representing the signal. Supported types: float, double, long, int and short.

Since: 0.01.6

Member Function Documentation

◆ projectSignal()

template<class NUMTYPE = float>

virtual bool gcgBASIS1D< NUMTYPE >::projectSignal	(	int	atX,
		gcgDISCRETE1D< float > *	vector,
		gcgDISCRETE1D< NUMTYPE > *	outputcoef
	)

privatepure virtual

Computes the coefficients of the projection of the 1D vector signal on the basis. It projects the number of samples of this basis (given by setNumberOfSamples()) starting at position atX of vector. The coefficients are stored in array outputcoef that is adjusted to have getNumberofCoefficients() coefficients.

Parameters

[in]	atX	origin of the signal for this projection (relative to vector origin).
[in]	vector	array (as 1D signal) containing components of the vector to be projected onto the basis.
[out]	outputcoef	array (as 1D signal) that receives the computed coefficients. It is adjusted to have getNumberofCoefficients() elements.

Returns: true if projection is successful.

Implemented in gcgDWTBASIS1D< NUMTYPE >, and gcgLEGENDREBASIS1D< NUMTYPE >.

◆ reconstructSignal()

template<class NUMTYPE = float>

virtual bool gcgBASIS1D< NUMTYPE >::reconstructSignal	(	int	atX,
		gcgDISCRETE1D< NUMTYPE > *	inputcoef,
		gcgDISCRETE1D< float > *	outputvector
	)

privatepure virtual

Computes the components of a vector (as 1D signal), using the getNumberofCoefficients() coefficients given in array inputcoef. The components (up to the number of samples given by setNumberOfSamples())are stored in the 1D signal outputvector starting at position atX.

Parameters

[in]	atX	origin of the signal for this projection (relative to outputvector origin).
[in]	inputcoef	input array of coefficients (as 1D signal) representing the vector to be reconstructed.
[out]	outputvector	array (as 1D signal) that receives the reconstructed samples starting at position atX.

Returns: true if reconstruction is successful.

◆ setNumberOfSamples()

template<class NUMTYPE = float>

virtual bool gcgBASIS1D< NUMTYPE >::setNumberOfSamples ( unsigned int nsamples )

privatepure virtual

Sets the number of samples to be used in projection and reconstruction processes.

Parameters

[in] nsamples number of samples to be used in projection and reconstruction processs. Depending on the basis, it might be used to discretize functions to speed up scalar products.

Returns: true if setup is successful.

Implemented in gcgDWTBASIS1D< NUMTYPE >, and gcgLEGENDREBASIS1D< NUMTYPE >.
