Constructor & Destructor Documentation

firevision::RcdCircleModel::RcdCircleModel	(	unsigned int	max_failures = 300,
		unsigned int	min_pixels = 20,
		unsigned int	min_interpix_dist = 10,
		unsigned int	max_dist_p4 = 2,
		unsigned int	max_dist_a = 10,
		float	hw_ratio = 0.6,
		float	hollow_rate = 0.f,
		float	max_time = 0.01
	)

Create a new circle model which uses RCD to detect circles.

Parameters:

	max_failures	Max. number of failures
	min_pixels	Min number of available edge pixels
	min_interpix_dist	Min distance between chosen pixels
	max_dist_p4	Max. distance of fourth pixel to circle
	max_dist_a	Max. distance for all other pixels to circle
	hw_ratio	Ratio height/width
	hollow_rate	size of the hollow window in the ROI.
	max_time	Maximum runtime per loop
