Detailed Description

template<class I, template< typename > class N = CDefaultFilterPolicy>
class mds::img::CLaplaceFilter5< I, N >

Laplacian image filter (4-th version).

• Parameter I is a used image type.
• Policy N is used for filter response normalization.
• Kernel definition:
  [ 0 0 -1 0 0 ]
  1 [ 0 -1 -2 -1 0 ]
  -- [ -1 -2 16 -2 -1 ]
  16 [ 0 -1 -2 -1 0 ]
  [ 0 0 -1 0 0 ]

Member Function Documentation

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

CLaplaceFilter5< I, N >::tResult CLaplaceFilter5::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 = CDefaultFilterPolicy>

tSize mds::img::CLaplaceFilter5< I, N >::getSize

(

)

const

Returns filter standard deviation.

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>

bool CLaplaceFilter5::operator()	(	const tImage &	SrcImage,
		tImage &	DstImage
	)

Filtering of input/source image.

Point filter responses are written to the destination image.

• Returns false on failure.
