Detailed Description

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

Aim: Implementation of the linear in time Power map construction.

Description of template class 'PowerMap'

The algorithm uses a separable process to construct Power maps as discussed in [27]. Along periodic dimensions, the algorithm is adapted following [34].

Given an image mapping points to values and a power separable metric, the class computes the power map of the weighted points specified in the image. Similarly to the VoronoiMap class, if two points are equi-distant according to the power distance, this power map will only consider one of them.

By default, the domain is considered non-periodic but per-dimension periodicity can be specified in the constructor. When the domain has periodic dimensions, the closest point coordinates B to a given point A may not be between the lower and upper bounds of the domain, in such a way that the non-periodic power distance between A and B is equal to their power distance considering the periodicity.

If the separable metric has a complexity of O(h) for its "hiddenByPower" predicate, the overall Power map construction algorithm is in \( O(h.d.n^d)\) for \( n^d\) domains (see class constructor). For Euclidean the \( l_2\) metric, the overall computation is in \( O(d.n^d)\), which is optimal.

This class is a model of concepts::CConstImage.

Note
if weights come from distance transform values, do not forget to square the distance values (for the l2 metric). I.e: \( w_i(c_i)=r_i^2\) for a ball \(B_i(c_i,r_i)\).
