Member Function Documentation

virtual::itk::LightObject::Pointer itk::RegularStepGradientDescentOptimizer::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::RegularStepGradientDescentBaseOptimizer.

virtual const char* itk::RegularStepGradientDescentOptimizer::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

Reimplemented from itk::RegularStepGradientDescentBaseOptimizer.

static Pointer itk::RegularStepGradientDescentOptimizer::New ( )
static

Method for creation through the object factory.

void itk::RegularStepGradientDescentOptimizer::operator= ( const Self )
private
virtual void itk::RegularStepGradientDescentOptimizer::StepAlongGradient ( double  factor,
const DerivativeType transformedGradient 
)
overrideprotectedvirtual

Advance one step along the corrected gradient taking into account the steplength represented by factor. This method is invoked by AdvanceOneStep. It is expected to be overrided by optimization methods in non-vector spaces
