Several of the results presented in this paper can be improved upon.
When detecting bees in a segmented image,
it could be beneficial to attempt to fit an ellipse over the
detected regions. This should help to reduce cases where a
single bee causes multiple detections due to the foreground
being fragmented into small, incomplete regions. Doing so
could also help prevent scenarios where multiple bees are
included in a single detection. Not only will this improve
detection results, but it should also improve the accuracy in
determining arrivals and departures by reducing redundant
tracks crossing the entrance boundary.
