Iterative hysteresis
We will do the iterative process with connected components (CC):
- Take a mask of combined weak and strong edges and run CC algorithm on it.
- For each such CC group- test if there is intersection with ONLY strong edges mask.
- If intersection exist, then weak edges in CC group is actually strong edges, so unite the masks.
