Description of template class 'LocalEstimatorFromSurfelFunctorAdapter'
When we evaluate the adapted estimator at a surfel s, we first identify the set of neighboring around s using a DistanceBreadthFirstVisitor parametrized by a given metric. Then, the estimated quantity is computed applying a functor on the surfel set.
More precisely, this adapter needs a model of CMetricSpace to define the neighborhood and a model of CLocalEstimatorFromSurfelFunctor to perform the local estimator computation. When sent to the functor, the surfels are weighted using the distance from the kernel boundary: weights are defined in [0,1] interval, 1 for the center and decreasing to 0 with the distance to the specified kernel radius specified during the init(). The shape of the distance-to-weight function is defined by a functor of type TConvolutionFunctor.
During the init() method, we thus specify the gridstep h and the radius of the ball to consider to define the neighborhood. An instance of the convolution functor should be passed to the constructor.
Note that the visitor used in this class considers the distance function in the ambient space (not a geodesic one for instance) on canonical embedding of surfel elements (cf CanonicSCellEmbedder).
