template<typename L, typename I, typename N>

mln::trait::ch_value< I, L >::ret mln::morpho::watershed::flooding	(	const Image< I > &	input,
		const Neighborhood< N > &	nbh
	)			[inline]

Meyer's Watershed Transform (WST) algorithm, with no count of basins.

Parameters:

[in]	input	The input image.
[in]	nbh	The connexity of markers.

• L is the type of labels, used to number the watershed itself (with the minimal value), and the basins.
• I is the exact type of the input image.
• N is the exact type of the neighborhood used to express input's connexity.

Note that the first parameter, L, is not automatically valued from the type of the actual argument during implicit instantiation: you have to explicitly pass this parameter at call sites.

mln::trait::ch_value< I, L >::ret mln::morpho::watershed::flooding	(	const Image< I > &	input,
		const Neighborhood< N > &	nbh,
		L &	n_basins
	)			[inline]

Meyer's Watershed Transform (WST) algorithm.

Parameters:

[in]	input	The input image.
[in]	nbh	The connexity of markers.
[out]	n_basins	The number of basins.

• L is the type of labels, used to number the watershed itself (with the minimal value), and the basins.
• I is the exact type of the input image.
• N is the exact type of the neighborhood used to express input's connexity.
