◆ addVote()

template<typename PointT >
void pcl::features::ISMVoteList< PointT >::addVote ( pcl::InterestPoint in_vote,
const PointT vote_origin,
int  in_class 
)

This method simply adds another vote to the list.

Parameters
[in]in_votevote to add
[in]vote_originorigin of the added vote
[in]in_classclass for which this vote is cast

◆ findStrongestPeaks()

template<typename PointT >
void pcl::features::ISMVoteList< PointT >::findStrongestPeaks ( std::vector< ISMPeak, Eigen::aligned_allocator< ISMPeak > > &  out_peaks,
int  in_class_id,
double  in_non_maxima_radius,
double  in_sigma 
)

This method finds the strongest peaks (points were density has most higher values).

It is based on the non maxima suppression principles.

Parameters
[out]out_peaksit will contain the strongest peaks
[in]in_class_idclass of interest for which peaks are evaluated
[in]in_non_maxima_radiusnon maxima suppression radius. The shapes radius is recommended for this value.
in_sigma

Returns the colored cloud that consists of votes for center (blue points) and initial point cloud (if it was passed).

Parameters
[in]cloudcloud that needs to be merged with votes for visualizing.
