Detailed Description
template<unsigned N>
class rgrl_feature_set_bins< N >
A set of features grouped only by N-d location.
This class is used to store a collection of discrete features for which proximity is determined only by location. There is no concepts of "segments"; each feature is considered independent.
The class is templated over the dimension in order to provide efficient implementation of the queries.
The underlying data structure is either rdsl_bins or rsdl_kd_tree. when using rsdl_bins, the image region is divided into rectangular bins, with the bin_size defaulted to 10 or defined by the user during construction. Feature point locations and associated values are stored in a list associated with the bin the location falls into. When performing region searches, all bins that intersect the query region are examined. When doing nearest-neighbor searches, spiral search is performed, starting at the bin containing the query point. rsdl_bins is the choice if the data is well distributed.
rsdl_kd_tree is multi-dimensional version of binary search tree. It handles data clustering better than rsdl_bins. Example applications include range data registration.

| 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.
