Constructor Details

CalculateHistogram

public CalculateHistogram(int energyIndex)

Creates a new CalculateHistogram instance.

Parameters:

energyIndex - The index of the energy channel to calculate the histogram from.

Method Details

execute

protected Histogram execute(FeatureInputStack input)
                     throws FeatureCalculationException

Description copied from class: CalculationPart

This performs the actual calculation when needed. It should only be called once, until CalculationPart.invalidate() is called.

Specified by:
