Detailed Description

This class is used to add constraints to any multi valued model fit cost function.

MVConstrainedCostFunctionDecorator is used to extend a given cost function with the functionality to regard given constraints for the measure. To add this functionality to a cost function, instantiate the decorator, set the wrapped cost function (that will be extended) and set a constraint checker that defines the type of constraints.
The decorator has a failure threshold. An evaluation can always be accounted as a failure if the sum of penalties given by the checker is greater or equal to the threshold. If the evaluation is a failure the wrapped cost function will not be evaluated. Otherwise the penalty will be added to every measure of the cost function.

CalcMeasure()

virtual

GetEvaluationCount()

virtual unsigned int mitk::MVConstrainedCostFunctionDecorator::GetEvaluationCount ( ) const

virtual

Returns the number of evaluations done by the cost function instance since creation.

GetFailedParameter()

ParametersType::size_type mitk::MVConstrainedCostFunctionDecorator::GetFailedParameter

(

)

const

Returns the index of the first (in terms of index position) failed parameter in the last failed evaluation.

GetFailureRatio()

double mitk::MVConstrainedCostFunctionDecorator::GetFailureRatio

(

)

const

Returns the ration between evaluations that where beyond the failure thershold and all evaluation since creation of the instance. 0.0 means no evaluation was a failure (but some may be penalized); 1.0 all evaluations were failures.

GetFailureThreshold()

virtual PenaltyValueType mitk::MVConstrainedCostFunctionDecorator::GetFailureThreshold ( ) const

virtual

GetPenaltyRatio()

double mitk::MVConstrainedCostFunctionDecorator::GetPenaltyRatio

(

)

const

Returns the ration between evaluations that were penaltized and all evaluation since creation of the instance. 0.0 means no evaluation was penalized; 1.0 all evaluations were. (evaluations that hit the failure threshold count as penalized too.)
