Member Function Documentation

void SpinImageGeneric::computeNeighborhoodFeature	(	const sensor_msgs::PointCloud &	data,
		const std::vector< int > &	neighbor_indices,
		const unsigned int	interest_sample_idx,
		std::vector< float > &	result
	)		const `[protected, virtual]`

Computes the spin image descriptor for the given neighborhood of points.

Parameters:

data	The overall point cloud data
neighbor_indices	List of indices in data that constitute the neighborhood
interest_sample_idx	The interest point/region that is being processed.
result	The vector to hold the resulting spin image feature vector

Implements NeighborhoodFeature.
