Detailed Description

template<typename PointInT, typename PointNT, typename PointOutT>
class pcl::PPFEstimation< PointInT, PointNT, PointOutT >

Class that calculates the "surflet" features for each pair in the given pointcloud.

Please refer to the following publication for more details: B. Drost, M. Ulrich, N. Navab, S. Ilic Model Globally, Match Locally: Efficient and Robust 3D Object Recognition 2010 IEEE Conference on Computer Vision and Pattern Recognition (CVPR) 13-18 June 2010, San Francisco, CA

PointOutT is meant to be pcl::PPFSignature - contains the 4 values of the Surflet feature and in addition, alpha_m for the respective pair - optimization proposed by the authors (see above)
