class pcl::ISSKeypoint3D< PointInT, PointOutT, NormalT >
ISSKeypoint3D detects the Intrinsic Shape Signatures keypoints for a given point cloud.
This class is based on a particular implementation made by Federico Tombari and Samuele Salti and it has been explicitly adapted to PCL.
For more information about the original ISS detector, see:

double model_resolution;
iss_detector.
compute (*model_keypoints);
