class pcl::UniqueShapeContext< PointInT, Eigen::MatrixXf, PointRFT >

UniqueShapeContext implements the Unique Shape Descriptor described here:

F. Tombari, S. Salti, L. Di Stefano, "Unique Shape Context for 3D data description", International Workshop on 3D Object Retrieval (3DOR 10) - in conjuction with ACM Multimedia 2010

The USC computed feature has the following structure:

rf float[9] = x_axis | y_axis | normal and represents the local frame desc std::vector<float> which size is determined by the number of bins radius_bins_, elevation_bins_ and azimuth_bins_.
