[Insight-users] Question About ThresholdCalculator

[Jianxu Chen]

Hello,

Could anyone help me on using "TriangleThresholdCalculator"? My question is
how can I convert the output of TriangleThresholdCalculator into a float
variable so that it can be used as a threshold of
ConnectedThresholdImageFilter?

The threshold-calculator is defined as following:

typedef itk::TriangleThresholdCalculator<
ScalarImageToHistogramGeneratorType::HistogramType>
TriangleThresholdCalculatorType;

 TriangleThresholdCalculatorType::Pointer calculator =
TriangleThresholdCalculatorType::New();

... ...

double  tri_threshold= calculator->GetOutput();  // There is an error here.
How to convert the type here?

Thanks in advance.
