Detailed Description

template<typename TDigitalSurface, typename TKernelFunctor>
class DGtal::deprecated::LocalConvolutionNormalVectorEstimator< TDigitalSurface, TKernelFunctor >

Aim: Computes the normal vector at a surface element by convolution of elementary normal vector to adjacent surfel.

Description of template class 'LocalConvolutionNormalVectorEstimator'

A model of CNormalVectorEstimator.

To each $n-1$ signed surfel, an elementary inward normal vector can be defined. At a given surfel, this estimator will compute the convolution of elementary normal vector of neighboring surfels using a breadth-first propagation around the given surfel.

The neighboring is parametrized by a given topological radius R. The weight kernel function maps displacment vectors to a continuous weights.

Warning
moved to deprecated since 0.7. Please consider using LocalEstimatorFromFunctorAdapter.
Template Parameters
TDigitalSurfacetype of digital surface on which we would like to compute vector field..
TKernelFunctortype of Functor used to represent convolution kernel functor (see BasicConvolutionKernels.h).
