Background subtraction, python, mog, gmg, opencv3.1

If it was written on the net, I couldn't use it as it was, so just a little.

I just added bgsegm.

 mog2 didn't work for some reason.

    cv2.imshow('frame',dst)

    k = cv2.waitKey(30) & 0xff
    if k == 27:  # ESC key
        break
cap.release()
cv2.destroyAllWindows()

gmg.py
