Detailed Description

Optimizer that fully samples a grid on the parametric space.

This optimizer is equivalent to an exahaustive search in a discrete grid defined over the parametric space. The grid parameters are define through an array of minimum and maximum values. The subdivisions of the grid along each one of the dimensions of the parametric space is defined by an array of number of steps. This optimizer is useful when its needed to plot the entire metric space to get an idea of how noisy it is etc...

A typical use of the optimizer is to plot the metric space to get an idea of how noisy it is. An example is given below, where it is desired to plot the metric space with respect to translations along x, y and z in a 3D registration application: Here it is assumed that the transform is Euler3DTransform.

 OptimizerType::StepsType steps( m_Transform->GetNumberOfParameters() );
 steps[1] = 0;  
 steps[2] = 0;  
 steps[3] = 0;  
 steps[3] = 10;
 steps[4] = 10;
 steps[5] = 10;
 m_Optimizer->SetNumberOfSteps( steps );
 m_Optimizer->SetStepLength( 2 );

The optimizer throws IterationEvents after every iteration. We use this to plot the metric space in an image as follows:

  if( itk::IterationEvent().CheckEvent(& event ) )
    {
    IndexType index;
    index[0] = m_Optimizer->GetCurrentIndex()[3];
    index[1] = m_Optimizer->GetCurrentIndex()[1];
    index[2] = m_Optimizer->GetCurrentIndex()[2];
    image->SetPixel( index, m_Optimizer->GetCurrentValue() );
    }

The image size is expected to be 21 x 21 x 21 with a spacing of 2.

If you wish to use different step lengths along each parametric axis, you can use the SetScales() method. This accepts an array, each element represents the number of subdivisions per step length. For instance scales of [0 0 0 0.5 1 4 ] along with a step length of 2 will cause the optimizer to search the metric space on a grid with x,y,z spacing of [1 2 8].

Member Function Documentation

unsigned long itk::Object::AddObserver ( const EventObject event,
Command  
) const [inherited]

unsigned long itk::Object::AddObserver ( const EventObject event,
Command  
) [inherited]

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

void itk::ExhaustiveOptimizer::AdvanceOneStep ( void   )  [protected]

Advance one step following the gradient direction This method verifies if a change in direction is required and if a reduction in steplength is required.

static void itk::LightObject::BreakOnError (  )  [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

virtual LightObject::Pointer itk::Object::CreateAnother (  )  const [virtual, inherited]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

virtual void itk::Object::DebugOff (  )  const [virtual, inherited]

Turn debugging output off.

virtual void itk::Object::DebugOn (  )  const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete (  )  [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

Command* itk::Object::GetCommand ( unsigned long  tag  )  [inherited]

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

virtual const CostFunctionType* itk::SingleValuedNonLinearOptimizer::GetCostFunction (  )  [virtual, inherited]

Get the cost function.

virtual const ParametersType& itk::ExhaustiveOptimizer::GetCurrentIndex (  )  [virtual]
