what‘’s the performance compared with Mask RCNN on object detection?

[scut-salmon]

Hi, I find that UPSNet mainly add an semantic segmentation head to mask RCNN, I wonder what's the performance of UPSNet on object detection(or instance segmentation). Can I use it to improve my object detection MAP? Sorry but I didn't find this discuss in your paper.

I would be appreciated if you could give me some advice, thanks.
