function
MinSG::Evaluators::OverdrawFactorEvaluator::getResultQuantile

public const inline
   
   
double getResultQuantile( ) const

Return the quantile that is used to calculate a single value from all the values in the image. A value of 0.0 corresponds to the minimum, 0.5 to the median, and 1.0 to the maximum.

Returns

Value in [0, 1]
