void mln::morpho::tree::filter::direct	(	const T &	tree,
		Image< F > &	f_,
		const Function_v2b< P > &	pred_
	)			[inline]

Direct non-pruning strategy.

A node is removed if it does not verify the predicate. The sub-components remain intact.

Parameters:

[in]	tree	Component tree.
[out]	f_	Image to filter.
[in]	pred_	Filtering criterion.

Definition at line 73 of file direct.hh.

template<typename T , typename F , typename P >

void mln::morpho::tree::filter::filter	(	const T &	tree,
		Image< F > &	f_,
		const Function_v2b< P > &	pred_,
		const typename F::value &	v
	)			[inline]

Filter the image f_ with a given value.

The sub-components of nodes that does not match the predicate pred_ are filled with the given value v.

Parameters:

	tree	Component tree.
	f_	Image function.
	pred_	Predicate.
	v	Value to propagate.

template<typename T , typename F , typename P >

void mln::morpho::tree::filter::max	(	const T &	tree,
		Image< F > &	f_,
		const Function_v2b< P > &	pred_
	)			[inline]

Max pruning strategy.

A node is removed iif all of its children are removed or if it does not verify the predicate pred_.

Parameters:

[in]	tree	Component tree.
[out]	f_	Image to filter.
[in]	pred_	Filtering criterion.

template<typename T , typename F , typename P >

void mln::morpho::tree::filter::min	(	const T &	tree,
		Image< F > &	f_,
		const Function_v2b< P > &	pred_
	)			[inline]

Min pruning strategy.

A node is removed iif its parent is removed or if it does not verify the predicate pred_.

Parameters:

[in]	tree	Component tree.
[out]	f_	Image to filter.
[in]	pred_	Filtering criterion.

template<typename T , typename F , typename P >

void mln::morpho::tree::filter::subtractive	(	const T &	tree,
		Image< F > &	f_,
		const Function_v2b< P > &	pred_
	)			[inline]

Subtractive pruning strategy.

The node is removed if it does not verify the predicate. The sub-components values are set to the value of the removed component.

Parameters:

[in]	tree	Component tree.
[out]	f_	Image to filter.
[in]	pred_	Filtering criterion.
