Name	Description
TCVN_CCM_DEFAULT	4pi * area / perimeter^2
TCVN_CCM_CONVEXHULL_PERIMETER	4pi * area / (convex hull perimeter)^2
TCVN_CCM_MAX_RADIUS	area / (pi * r^2), r = max distance to the contour's center of mass
TCVN_CCM_ENCLOSINGCIRCLE_RADIUS	area / (pi * r^2), r = radius of the minimum enclosing circle
