Detailed Description

template<typename TWeightImage, typename TPSeparableMetric, typename TImageContainer = ImageContainerBySTLVector<HyperRectDomain<typename TWeightImage::Domain::Space>, typename TWeightImage::Domain::Space::Vector>>
class DGtal::ReverseDistanceTransformation< TWeightImage, TPSeparableMetric, TImageContainer >

Aim: Implementation of the linear in time reverse distance transformation for separable metrics.

Description of template class 'ReverseDistanceTransformation'

This class is a wrapper around a power map construction (see PowerMap). More precisely, at a point p, since the PowerMap at p returns a vector to the closest power site, this class adapts the operator() in order to returns the power distance to the closest weighted site for the considered metric.

Please refer to PowerMap documentation for details on the computational cost and parameter description.

This class is a model of CConstImage.

Template Parameters
TWeightImagemodel of CConstImage
TPSeparableMetricmodel of CPowerSeparableMetric
TImageContainerany model of CImage to store the PowerMap (default: ImageContainerBySTLVector). The space of the image container and the TSpace should match. Furthermore the container value type must be TSpace::Vector.
