Function Documentation

template<typename A, typename I>

A::result mln::accu::compute	(	const Accumulator< A > &	a,
		const Image< I > &	input
	)			[inline]

Make an accumulator compute the pixels of the image input.

Parameters:

[in]	input	The input image.
[in]	a	An accumulator.

This routine runs:
a.take(make::pix(input, p)); on all pixels on the images.

Warning:

This routine does not perform a.init().

template<typename Meta_Accu, unsigned Dir, typename I, typename O>

void mln::accu::line	(	const Image< I > &	input,
		const typename I::site &	p_start,
		unsigned	len,
		unsigned	half_length,
		Image< O > &	output
	)			[inline]

Line an accumulator onto the pixel values of the image input.

Parameters:

[in]	input	The input image.
[in]	p_start	The starting site of the line.
[in]	len	The line length.
[in]	half_length	The half length of the line.
[in,out]	output	The resulting image.

This routine runs:
tmp = a
tmp.init()
accu::take(input, tmp)
return tmp.to_result()

template<typename A, typename I>

mln::accu::mln_meta_accu_result	(	A	,
		util::pix< I >
	)			const [inline]

Make an accumulator compute the pixels of the image input.

Parameters:

[in]	input	The input image.
[in]	a	A meta accumulator.

This routine runs:
a.take(make::pix(input, p)); on all pixels on the images.

Warning:

This routine does not perform a.init().

template<typename A, typename I>

void mln::accu::take	(	const Image< I > &	input,
		Accumulator< A > &	a
	)			[inline]

Make an accumulator take the pixels of the image input.

Parameters:

[in]	input	The input image.
[in,out]	a	The accumulator.

This routine runs:
for all p of input, a.take( pix(input, p) )

Warning:

This routine does not perform a.init().
