Detailed Description

template<class NUMTYPE = float>
class gcgBASIS2D< NUMTYPE >

Abstract class for 2D 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 gcgBASIS2D< NUMTYPE >::projectSignal ( int  atX, int  atY, gcgDISCRETE2D< float > *  vector, gcgDISCRETE1D< NUMTYPE > *  outputcoef  )

privatepure virtual

Computes the coefficients of the projection of the 2D signal vector on the 2D basis. The coefficients are stored in array outputcoef that will be ajusted to have getNumberofCoefficients() coefficients.

Parameters

[in]	atX	origin X coordinate of the signal for this projection (relative to vector).
[in]	atY	origin Y coordinate of the signal for this projection (relative to vector).
[in]	vector	2D 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.

virtual bool gcgBASIS2D< NUMTYPE >::reconstructSignal ( int  atX, int  atY, gcgDISCRETE1D< NUMTYPE > *  inputcoef, gcgDISCRETE2D< float > *  outputvector  )

privatepure virtual

Computes the components of a 2D vector, using the getNumberofCoefficients() coefficients given in array inputcoef (as 1D signal). The components are stored in the 2D signal outputvector starting at position (atX, atY).

Parameters

[in]	atX	origin X coordinate of the signal for this projection (relative to outputvector).
[in]	atY	origin Y coordinate of the signal for this projection (relative to outputvector).
[in]	inputcoef	array of coefficients (as 1D signal) representing the vector to be reconstructed.
[out]	outputvector	array (as 2D signal) that receives the reconstructed samples starting at position (atX, atY).

Returns

true if reconstruction is successful.
