Parameters

Name	Type	Range	Default	Description
inImage	const Image&			Input image
inRoi	Optional<const Region&>		NIL	Range of pixels to be processed
inCircleRadius	float	1.0 -		Circle radius measured in input image pixels.
inWorldCircleSpacing	float	0.0 -	1.0f	Real-world distance between adjacent circles centers.
inCircleDetectionThreshold	float	- -	20.0f	Detection threshold (relative to local image patch).
inCirclePolarity	Polarity::Type		Any	Circle intensity with respect to background.
outImagePoints	Array<Point2D>&			Image coordinates of detected calibration points.
outWorldPlanePoints	Array<Point2D>&			World plane coordinates of detected calibration points.
diagCirclesRegion	Region&			Image after thresholding, this is the circle detector input.
diagCircleCandidates	Array<Point2D>&			Detected circle centers, before the grid construction step.
