Constructor & Destructor Documentation

IntervalForegroundPredicate() [1/2]

template<typename Image >

DGtal::functors::IntervalForegroundPredicate< Image >::IntervalForegroundPredicate ( ConstAlias< Image > aImage, const Value minVal, const Value maxVal )

inline

Constructor. This functor can be used to threshold image values in the interval ]minVal,maxVal].

Parameters

aImage	the image.
minVal	the minimum value (first value excluded).
maxVal	the maximum value (last value considered).

Definition at line 80 of file IntervalForegroundPredicate.h.
