Detailed Description

template<class I, template< typename > class N = CDefaultFilterPolicy>
class mds::img::CDoGFilter< I, N >

Difference of Gaussians image filter.

• Parameter I is a used image type.
• Policy N is used for filter response normalization.

Member Function Documentation

template<class I , template< typename > class N = CDefaultFilterPolicy>

tResult mds::img::CDoGFilter< I, N >::getResponse	(	const tImage &	SrcImage,
		tSize	x,
		tSize	y
	)

Returns filter response at specified image point.

• Value is not normalized!

template<class I , template< typename > class N>

void CDoGFilter::getSigmas	(	double &	dSigma1,
		double &	dSigma2
	)		const

Returns filter standard deviations.

template<class I , template< typename > class N>

bool CDoGFilter::operator()	(	const tImage &	SrcImage,
		tImage &	DstImage
	)

Filtering of input/source image.

Point filter responses are written to the destination image.

• Returns false on failure.

virtual bool mds::img::CNormImageFilter< I, N >::operator()	(	const tImage &	SrcImage,
		tImage &	DstImage
	)		[pure virtual, inherited]

Filtering of input/source image.

• Returns false on failure.

Implements mds::img::CImageFilter< I >.

template<class I , template< typename > class N>

void CDoGFilter::setSigmas	(	double	dSigma1,
		double	dSigma2
	)

Sets the standard deviations.
