mln::trait::concrete< I >::ret mln::linear::gaussian::filter	(	const Image< I > &	input,
		double	sigma
	)			[inline]

Gaussian filter of an image input.

Precondition:

output.domain = input.domain

Apply an approximated gaussian filter of sigma on input. This filter is applied in all the input image direction.

Precondition:

input.is_valid

template<typename I >

mln::trait::concrete< I >::ret mln::linear::gaussian::filter	(	const Image< I > &	input,
		double	sigma,
		int	dir
	)			[inline]

Apply an approximated gaussian filter of sigma on input. on a specific direction dir if dir = 0, the filter is applied on the first image dimension. if dir = 1, the filter is applied on the second image dimension. And so on...

Precondition:

input.is_valid

dir < dimension(input)
