Detailed Description

template<class PixelType>
class rgrl_matcher_pseudo< PixelType >

For each "from" pseudo / weak feature, use intensity based matching to construct the "to" features.

This will map the "from" feature and its surrounding region using the current transformation, and search for the best intensity-region match to construct the "to" feature.

EvaluatorType, which perhaps should be a base class, takes two voxel lists and calculates a similarity measure between them. This says how well two subregions match. (F in notes)

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.
