Detailed Description

template<typename Image>
class DGtal::functors::SimpleThresholdForegroundPredicate< Image >

Aim: Define a simple Foreground predicate thresholding image values given a single thresold. More precisely, the functor operator() returns true if the value is greater than a given threshold.

Description of template class 'SimpleThresholdForegroundPredicate'

This class is a model of concepts::CPointPredicate.

Template Parameters

Image

an model of CConstImage concept.

Examples:

examples/tutorial-examples/polyhedralizer.cpp, geometry/volumes/distance/distancetransform2D.cpp, geometry/volumes/distance/distancetransform3D.cpp, geometry/volumes/distance/toricdomainvolumetric.cpp, tutorial-examples/polyhedralizer.cpp, and tutorial-examples/volDTGranulo.cpp.
