bool pcl::Narf::extractFromRangeImage ( const RangeImage range_image,
const Eigen::Affine3f &  pose,
int  descriptor_size,
float  support_size,
int  surface_patch_world_size = NARF_DEFAULT_SURFACE_PATCH_PIXEL_SIZE 
)

Method to extract a NARF feature from a certain 3D point using a range image. pose determines the coordinate system of the feature, whereas it transforms a point from the world into the feature system. This means the interest point at which the feature is extracted will be the inverse application of pose onto (0,0,0). descriptor_size_ determines the size of the descriptor, support_size determines the support size of the feature, meaning the size in the world it covers
