Detailed Description

For each "from" feature, match the k nearest "to" features.

This will map the "from" feature via the current transform and select the k nearest "to" features to the mapped "from" feature.

The some of the nearest features can optionally be discarded if it is further than some threshold distance.

Member Function Documentation

unsigned int rgrl_object::add_observer	(	rgrl_event_sptr	event,
		rgrl_command_sptr	cmd
	)		[inherited]

Allow people to add/remove/invoke observers (callbacks) to any rgrl object.

This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an rgrl_command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command.

Definition at line 47 of file rgrl_object.cxx.

void rgrl_matcher_k_nearest::add_one_flipped_match	(	rgrl_match_set_sptr &	inv_set,
		rgrl_view const &	current_view,
		nodes_vec_iterator const &	begin_iter,
		nodes_vec_iterator const &	end_iter
	)		[protected, virtual]

This is internal to invert matches function.

It is to restrict the number of nearest neighbors
