Now the opencv vectorization is invoked with fixed approximation parameters, and if we make epsilon=0.0 it will only affect the second stage of contour simplification.
It is better to allow cv2.APPROX_SIMPLE in find_contours, because it may give better results with small and jagged pixel boundaries, because it will not create sharp angles.
