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.

Estimates homography transformation.

| rgrl_transformation_sptr rgrl_estimator::estimate | ( | rgrl_match_set_sptr | matches, |
| rgrl_transformation const & | cur_transform | ||
| ) | const [virtual, inherited] |
Estimate the transform.
Given a set of matches in matches and the current transform estimate (from the previous iteration, for example), this function will estimate the transformation parameters and return a transform object that captures the estimated transform.
The default implementation in the abstract base class will simply construct a size one collection of match sets and call the other estimate function.

Definition at line 97 of file rgrl_object.cxx.
| virtual unsigned int rgrl_estimator::residual_dof | ( | ) | const [inline, virtual, inherited] |
The degrees of freedom in the residual.
Most of the time, this would be 1 since the residual comes from a single random variable. In some problems, however, the error is the combination of more than one random variable. (For example, if the residual is a 2d Euclidean distance with possible error in both coordinates, the degrees of freedom in the error will be 2.)
