Detailed Description

template<typename PointInT, typename PointOutT>
class pcl::MomentInvariantsEstimation< PointInT, PointOutT >

MomentInvariantsEstimation estimates the 3 moment invariants (j1, j2, j3) at each 3D point.

Note
The code is stateful as we do not expect this class to be multicore parallelized. Please look at NormalEstimationOMP for an example on how to extend this to parallel implementations.
