Detailed Description

template<class I>
class mds::img::CAvg7Filter< I >

Averaging image filter (7x7 version).

• Parameter I is a used image type.
• Policy N is used for filter response normalization.
• Kernel definition:
  [ 1 2 3 4 3 2 1 ]
  [ 2 4 6 8 6 4 2 ]
  1 [ 3 6 9 12 9 6 3 ]
  --- [ 4 8 12 16 12 8 4 ]
  256 [ 3 6 9 12 9 6 3 ]
  [ 2 4 6 8 6 4 2 ]
  [ 1 2 3 4 3 2 1 ]

Member Function Documentation

template<class I >

CAvg7Filter< I >::tPixel CAvg7Filter::getResponse	(	const tImage &	SrcImage,
		tSize	x,
		tSize	y
	)

Returns filter response at specified image point.

(

)

const

Returns filter standard deviation.

template<class I >

bool CAvg7Filter::operator()	(	const tImage &	SrcImage,
		tImage &	DstImage
	)		[virtual]
