py_eddy_tracker.poly.vertice_overlap

py_eddy_tracker.poly.vertice_overlap(x0, y0, x1, y1, minimal_area=False)

Return percent of overlap for each item.

Parameters

• x0 (array) – x for polygon list 0

• y0 (array) – y for polygon list 0

• x1 (array) – x for polygon list 1

• y1 (array) – y for polygon list 1

• minimal_area (bool) – If True, function will compute intersection/little polygon, else intersection/union

Returns

Result of cost function

Return type

array

By default

\[Score = \frac{Intersection(P_0,P_1)_{area}}{Union(P_0,P_1)_{area}}\]

If minimal area:

\[Score = \frac{Intersection(P_0,P_1)_{area}}{min(P_{0 area},P_{1 area})}\]
