distance_cc — Calculate the distance between two contours.
The operator distance_cc calculates the minimum and maximum distance between the base points of two contours ( Contour1 and Contour2). The parameters DistanceMin and DistanceMax contain the resulting distance.
The parameter Mode sets the type of computing the distance: 'point_to_point' only determines the minimum and maximum distance between the base points of the contours. This results in faster algorithm but may lead to inaccurate minimum distances. In contrast, 'point_to_segment' determines the actual minimum distance of the contour segments.
In both cases, the search algorithm has a quadratic complexitity (n*n). If only the minimum distance is required, the operator distance_cc_min can be used alternatively since it offers algorithms with a complexity of 'n*log(n)'.
Both input parameters must contain the same number of contours.
