Detailed Description

VFHEstimation estimates the Viewpoint Feature Histogram (VFH) descriptor for a given point cloud dataset containing points and normals.

Note: The code is stateful as we do not expect this class to be multicore parallelized. Please look at FPFHEstimationOpenMP for examples on parallel implementations of the FPFH (Fast Point Feature Histogram).
