Constructor & Destructor Documentation

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
