Detailed Description

template<typename TImage, typename TSet>
class DGtal::L1LocalDistance< TImage, TSet >

Aim: Class for the computation of the L1-distance at some point p, from the available distance values of some points lying in the 1-neighborhood of p (ie. points at a L1-distance to p equal to 1).

Description of template class 'L1LocalDistance'

The computed value is merely the minimum over all the available distance values in the 1-neighborhood of p, plus one.

It is a model of CPointFunctor.

Template Parameters

TImage	model of CImage used for the mapping point-distance value
TSet	model of CDigitalSet for storing points whose distance value is known
