The symptom is currently losing face tracking at distance of approx 2 meters. the additional margin of 0.1 width and 0.1 height is only effective for short ranges (e.g. less than 1 meters) since the face is relatively large. For distances up to 2 meters, need additional margins approx 0.2 x width and 0.2 x height since the face is smaller For distances up to 3 meters , need additional margins approx 0.3 x width and 0.3 x height. For distances up to 4 meters, need additional margins approx 0.4 x width and 0.4 x height.
