Calculating and comparing the inner and outer hind boundary curves. Mid: Depth map of cow’s backside recorded from top view. Everything but the cow is set to zero (blue). Left/Right: The inner/outer hind boundary curve. The inner/outer hind boundary curve is calculated by following the columnwise black/grey arrows to the last/first nonzero pixel. As the cow’s tail is overhanging, the inner and outer hind boundary curve differ (marked as white lines).
