distance_cc_min — Calculate the minimum distance between two contours.
distance_cc_min calculates the minimum distance between two contours Contour1 and Contour2. The minimum distance is returned in DistanceMin.
The parameter Mode sets the type of computing the distance. 'point_to_point' determines the distance of the closest contour points, 'fast_point_to_segment' calculates the distance of the line segments adjacent to these points, and 'point_to_segment' determines the actual minimum distance of the contour segments.
While 'point_to_point' and 'fast_point_to_segment' are efficient algorithms with a complexity of n*log(n), 'point_to_segment' has quadratic complexity and thus takes a longer time to execute, especially for contours with many line segments.
Both input parameters must contain the same number of contours.
First input contour.
Second input contour.
