◆ 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

◆ 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_peaks	it will contain the strongest peaks
[in]	in_class_id	class of interest for which peaks are evaluated
[in]	in_non_maxima_radius	non maxima suppression radius. The shapes radius is recommended for this value.
	in_sigma
