Detailed Description

2D similarity transform estimator.

Constructor & Destructor Documentation

rgrl_est_reduced_quad2d::rgrl_est_reduced_quad2d ( ) [explicit]

Default constructor.

Does nothing. This constructor is adequate for algorithms that call estimate(.) function only. An example of the algorithm is the rgrl_feature_based_registration.

Definition at line 17 of file rgrl_est_reduced_quad2d.cxx.

rgrl_est_reduced_quad2d::rgrl_est_reduced_quad2d ( unsigned int  dimension,
double  condition_num_thrd = 0.0 
)

Constructor.

Takes the dimension of the dataset that the estimator will be applied on, and maybe the minimum number of samples to instantiate a fit. If num_samples_for_fit is not set, the number is automatically generated, assuming each component provides one constraint.

Definition at line 22 of file rgrl_est_reduced_quad2d.cxx.


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.

unsigned int rgrl_object::debug_flag ( ) const [inherited]

Get the value of the debug flag.

Definition at line 26 of file rgrl_object.cxx.

rgrl_transformation_sptr rgrl_est_reduced_quad2d::estimate ( rgrl_set_of< rgrl_match_set_sptr > const &  matches,
rgrl_transformation const &  cur_transform 
) const [virtual]

Estimates a 2D reduced_quadratic transform.

The return pointer is to a rgrl_trans_reduced_quad2d object.

See also:
rgrl_estimator::estimate

Implements rgrl_estimator.

Definition at line 38 of file rgrl_est_reduced_quad2d.cxx.

rgrl_transformation_sptr rgrl_est_reduced_quad2d::estimate ( rgrl_match_set_sptr  matches,
rgrl_transformation const &  cur_transform 
) const [virtual]

Estimates a 2D reduced_quadratic transform.

The return pointer is to a rgrl_trans_reduced_quad2d object.

See also:
rgrl_estimator::estimate

Reimplemented from rgrl_estimator.

Definition at line 232 of file rgrl_est_reduced_quad2d.cxx.

rgrl_command_sptr rgrl_object::get_command ( unsigned int  tag) [inherited]

Get the command associated with the given tag.

Definition at line 57 of file rgrl_object.cxx.

bool rgrl_object::has_observer ( const rgrl_event event) const [inherited]

Return true if an observer is registered for this event.

Definition at line 107 of file rgrl_object.cxx.

void rgrl_object::invoke_event ( const rgrl_event event) [inherited]

Call execute(.) on all the rgrl_commands observing this event id.

Definition at line 69 of file rgrl_object.cxx.

void rgrl_object::invoke_event ( const rgrl_event event) const [inherited]

Call execute(.) on all the rgrl_commands observing this event id.

The actions triggered by this call doesn't modify this object.

Definition at line 83 of file rgrl_object.cxx.

virtual bool rgrl_linear_estimator::is_iterative_method ( ) const [inline, virtual, inherited]

Linear estimator is non-iterative.

Implements rgrl_estimator.

Definition at line 152 of file rgrl_estimator.h.

virtual bool rgrl_object::is_type ( const vcl_type_info &  type) const [inline, virtual, inherited]

Reimplemented in rgrl_scale_estimator.

Definition at line 66 of file rgrl_object.h.

unsigned int rgrl_estimator::param_dof ( ) const [inline, inherited]

The degrees of freedom in the parameter set.

Definition at line 81 of file rgrl_estimator.h.

void rgrl_object::remove_observer ( unsigned int  tag) [inherited]

Remove the observer with this tag value.

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.)
