Detailed Description

template<class DataPoint, template< typename >typename _NeighborhoodFrame>
class Ponca::NoWeightFuncBase< DataPoint, _NeighborhoodFrame >

Base Weighting function that set uniform weight to all samples.

In contrast to DistWeightFunc with ConstantWeight, it does not check for scale range.

Template Parameters
_NeighborhoodFrameBase NeighborhoodFrame used to performs (or not) local basis conversion and maintain computation accuracy
