Detailed Description

Finds the local minima/maxima by iteratively choosing the minimum/maximum value in a neighborhood.

This optimizer is designed to operate on a monotonic cost function WITHOUT using gradient information (derivatives). The user must set the Neighborhood size, and optionally the connectivity.

Member Function Documentation

virtual void itk::IterateNeighborhoodOptimizer::AdvanceOneStep ( void )

virtual

Advance one step.

virtual::itk::LightObject::Pointer itk::IterateNeighborhoodOptimizer::CreateAnother ( ) const

virtual

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::SingleValuedNonLinearOptimizer.

virtual void itk::IterateNeighborhoodOptimizer::FullyConnectedOff ( )

virtual

Get/set whether the nieghborhood is defined by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOn.

virtual void itk::IterateNeighborhoodOptimizer::FullyConnectedOn ( )

virtual

Get/set whether the nieghborhood is defined by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOn.

virtual unsigned int itk::IterateNeighborhoodOptimizer::GetCurrentIteration ( ) const

virtual

Get the current iteration number.

virtual const double& itk::IterateNeighborhoodOptimizer::GetCurrentValue ( ) const

virtual

Get the current value.

virtual const bool& itk::IterateNeighborhoodOptimizer::GetFullyConnected ( ) const

virtual

Get/set whether the nieghborhood is defined by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOn.

virtual const bool& itk::IterateNeighborhoodOptimizer::GetMaximize ( ) const

virtual

Configure whether the local maxima or minima is found. The default is to minimize the cost function (maximize = false ).
