Computes the direct transform.

Parameters

spatialImage	Input image in spatial domain.
frequentialImage	Output image in frequential domain. Must be of the same size as spatialImage if domainFormat is EFrequentialDomainFormat::EFrequentialDomainFormat_Packed or twice the width (and same height) if it is EFrequentialDomainFormat::EFrequentialDomainFormat_ComplexExtended.

No scaling is applied, scaling applied in EFourierTransformer::InverseTransform.

domainFormat	Format of the output frequential image

No scaling is applied, scaling applied in EFourierTransformer::InverseTransform.

		eVision::EFourierImage &	frequentialImage ) const

Computes the direct transform.

Parameters

spatialImage	Input image in spatial domain.
frequentialImage	Output image in frequential domain. Must be of the same size as spatialImage if domainFormat is EFrequentialDomainFormat::EFrequentialDomainFormat_Packed or twice the width (and same height) if it is EFrequentialDomainFormat::EFrequentialDomainFormat_ComplexExtended.

No scaling is applied, scaling applied in EFourierTransformer::InverseTransform.

DirectTransform() [4/6]

void eVision::EFourierTransformer::DirectTransform	(	const eVision::EROIBW32f &	spatialImage,
		eVision::EFourierImage &	frequentialImage,
		eVision::EFrequentialDomainFormat	domainFormat ) const

Computes the direct transform.

Parameters

spatialImage	Input image in spatial domain.
frequentialImage	Output image in frequential domain. Must be of the same size as spatialImage if domainFormat is EFrequentialDomainFormat::EFrequentialDomainFormat_Packed or twice the width (and same height) if it is EFrequentialDomainFormat::EFrequentialDomainFormat_ComplexExtended.
domainFormat	Format of the output frequential image

No scaling is applied, scaling applied in EFourierTransformer::InverseTransform.

DirectTransform() [5/6]

void eVision::EFourierTransformer::DirectTransform	(	const eVision::EROIBW8 &	spatialImage,
		eVision::EFourierImage &	frequentialImage ) const

Computes the direct transform.

Parameters

spatialImage	Input image in spatial domain.
frequentialImage	Output image in frequential domain. Must be of the same size as spatialImage if domainFormat is EFrequentialDomainFormat::EFrequentialDomainFormat_Packed or twice the width (and same height) if it is EFrequentialDomainFormat::EFrequentialDomainFormat_ComplexExtended.

void eVision::EFourierTransformer::DirectTransform	(	const eVision::EROIBW8 &	spatialImage,
		eVision::EFourierImage &	frequentialImage,
		eVision::EFrequentialDomainFormat	domainFormat ) const

Computes the direct transform.

Parameters

spatialImage	Input image in spatial domain.
frequentialImage	Output image in frequential domain. Must be of the same size as spatialImage if domainFormat is EFrequentialDomainFormat::EFrequentialDomainFormat_Packed or twice the width (and same height) if it is EFrequentialDomainFormat::EFrequentialDomainFormat_ComplexExtended.
