Detailed Description

template<typename TPointPredicate, typename TDomain, typename TDigitalSetContainer = DigitalSetBySTLSet<TDomain>>
class DGtal::KanungoNoise< TPointPredicate, TDomain, TDigitalSetContainer >

Aim: From a point predicate (model of concepts::CPointPredicate), this class constructs another point predicate as a noisy version of the input one.

Description of template class 'KanungoNoise'

The noise model used here, called Kanungo noise, can be defined as follows: for each point on a domain, we compute the distance \( d \) to the "border" of the point predicate (see below) and the point label (true/false) is reverted with probability:

\[ \alpha^d \]

for \( 0< \alpha < 1\) specified at construction step.

Note: This class explicitely stores the noisy point predicate in a digital set container model. Furthermore, the distance is given by the DistanceTransformation class with the Eucliean metric (the distance is computed on both true and false points from the point predicate in the given domain).

Template Parameters

TPointPredicate	any model of point predicate concept (concepts::CPointPredicate)
TDomain	any model of CDomain
TDigitalSetContainer	container type to store the point predicate (default: DigitalSetBySTLSet)
