Detailed Description
template<typename PointInT, typename PointNT>
class pcl::PFHEstimation< PointInT, PointNT, Eigen::MatrixXf >
PFHEstimation estimates the Point Feature Histogram (PFH) descriptor for a given point cloud dataset containing points and normals.

- Attention:
- The convention for PFH features is:
- if a query point's nearest neighbors cannot be estimated, the PFH feature will be set to NaN (not a number)
- it is impossible to estimate a PFH descriptor for a point that doesn't have finite 3D coordinates. Therefore, any point that contains NaN data on x, y, or z, will have its PFH feature property set to NaN.
- Note:
- The code is stateful as we do not expect this class to be multicore parallelized. Please look at FPFHEstimationOMP for examples on parallel implementations of the FPFH (Fast Point Feature Histogram).
