Detailed Description

template<typename T, typename V>
class TCost< T, V >

The generic cost function interface.

The class defines an abstract interface for a cost function between two entities of the same type. The pure virtual functions -double do_value(const T& a, const T& b) const, and -double do_evaluate_force(const T& a, const T& b, float scale, V& force) const have to be implemented in the derived class to make it a real cost function. The virtual function

• void post_set_reference(const T& ref) may be overwritten in order to prepare the reference data for the implemented cost function.

  Template Parameters

  T	the data type of the objects that the cost evaluation is based on
  V	the type of the gradient force field created by this cost function

virtual TCost< T, V >::~TCost ( )

virtual

ensure virtual destruction, since we have virtual functions

Member Function Documentation

evaluate_force()

template<typename T , typename V >

double TCost< T, V >::evaluate_force	(	const T &	src,
		V &	force
	)		const

Evaluate the value of the cost function and its gradient with respect to the given src image and the reference that was set by calling set_reference(const T& ref).

Parameters

	src
[out]	force	gradient force

Returns

the cost function value

set_reference()

template<typename T , typename V >

void TCost< T, V >::set_reference

(

const T &

ref

)

Set the new reference of the cost function. The virtual private function post_set_reference(const T& ref) is then called to run possible preparations on the reference image.

value()

template<typename T , typename V >

double TCost< T, V >::value

(

const T &

src

)

const

Evaluate the value of the cost function petreen the given src image and the reference that was set by calling set_reference(const T& ref).

Parameters

src

Returns

the cost function value
