util::couple< mln_image_from_grid(mln_grid(P), D), mln_image_from_grid(mln_grid(P), unsigned)> mln::transform::distance_and_closest_point_geodesic	(	const p_array< P > &	pset,
		const box< P > &	closest_point_domain,
		const Neighborhood< N > &	nbh,
		D	max
	)			[inline]

Discrete geodesic distance transform.

Parameters:

[in]	pset	an array of sites.
[in]	closest_point_domain	domain of the returned image.
[in]	nbh	neighborhood
[in]	max	max distance of propagation.

Returns:

A couple of images. The first one is the distance map and the second one is the closest point image. The closest point image contains site indexes.

Postcondition:

The returned image domains are defined on closest_point_domain.

	)			[inline]

Discrete geodesic distance transform.

Parameters:

[in]	input	Image from which the geodesic distance is computed.
[in]	nbh	Neighborhood
[in]	max	Max distance of propagation.

Returns:

a couple of images. The first one is the distance map and the second one is the closest point image. The closest point image contains sites.

Postcondition:

The returned images have the same domain as input.

template<typename I>

image2d< float > mln::transform::hough

(

const Image< I > &

input_

)

[inline]

Compute the hough transform from a binary image.

Objects used for computation must be set to 'true'.

Parameters:

[in]

input_

A binary image.

Returns:

A 2D image of float. Rows are used for the distance and columns are used for the angles. Angles go from 0 to 359. Distance goes from 0 to the maximum distance between the center and a corner. The site having the maximum value indicates through its column index the document inclination.
