		eVision.EFourierImage	frequentialImage )

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.

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.

void eVision.EFourierTransformer.DirectTransform	(	eVision.EROIBW32f	spatialImage,
		eVision.EFourierImage	frequentialImage )

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	(	eVision.EROIBW32f	spatialImage,
		eVision.EFourierImage	frequentialImage,
		eVision.EFrequentialDomainFormat	domainFormat )

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.

void eVision.EFourierTransformer.DirectTransform	(	eVision.EROIBW8	spatialImage,
		eVision.EFourierImage	frequentialImage )

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.
