Constructor & Destructor Documentation

◆ SegmentAreaOp()

template<class S , class D , class T = SizeProber>

SegmentAreaOp	(	double	min = `1.0`,
		double	max = `std::numeric_limits<double>::max()`
	)

inline

min - the smallest intensity in a segment to be traversed

max - the largest intensity in a segment to be traversed

mapping - determines how the retrieved area is rescaled: d=direct, i=inversed, s=fuzzyScale, p=fuzzyPeak (was: f=fuzzyPeak)

scale - parameter depending on mapping

offset - parameter depending on mapping
