Detailed Description

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

Allows the same operations as for rgrl_matcher_k_nearest. For each center-location match, boundary points are extracted and stored as 2 matches.

FIXME: only deal with 2D for now.

rgrl_matcher_k_nearest_boundary::rgrl_matcher_k_nearest_boundary ( unsigned int k )

Initialize the matcher to select k correspondences per "from" feature.

rgrl_matcher_k_nearest_boundary::rgrl_matcher_k_nearest_boundary	(	unsigned int	k,
		double	dist_thres
	)

Select at most k correspondences within the threshold.

The matcher will select k correspondences from the list of correspondences with Euclidean distance within the threshold dist_thres.

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.

It is to restrict the number of nearest neighbors
