Function Documentation

template<typename identifier_t, typename pixel_value_t = unsigned char>

std::vector< pixel_value_t > Acts::HoughTransformUtils::PeakFinders::hitsCountImage	(	const HoughPlane< identifier_t > &	plane,
		typename HoughPlane< identifier_t >::Index	index,
		std::size_t	xSize,
		std::size_t	ySize,
		const std::function< pixel_value_t(const HoughPlane< identifier_t > &, int, int)> &	summaryFunction = [](const HoughPlane< identifier_t > &plane, int x, int y) { return static_cast< pixel_value_t >(plane.nHits(x, y));} )

Obtain an image around the peak.

Template Parameters

identifier_t Hough plane content

Parameters

plane	Hough plane to work on
index	peak center
xSize	number of cells around the peak in x direction
ySize	number of cells around the peak in y direction
summaryFunction	function constructing pixel content, default is just number of hits in cell Other implementations may take into account layers

Returns: the vector with count of hits starting from lower left to upper right corner of rectangular window The "image" is always of the same size, if it would happen to be outside of Hough plane the content is padded with zeros

template<typename identifier_t>

std::vector< typename HoughPlane< identifier_t >::Index > Acts::HoughTransformUtils::PeakFinders::slidingWindowPeaks	(	const HoughPlane< identifier_t > &	plane,
		const SlidingWindowConfig &	config )

Obtain peaks list in Hough space using Sliding Window algorithm.

Template Parameters

identifier_t Hough plane content

Parameters

plane	Hough plane to work on
config	algorithm configuration
