How much does detection performance affects the mAP and rank-k metrics?

Thanks for your awesome work!

As you mentioned, the mAP and Rank-k metric of different Faster-RCNN has a large gap.

origin faster-rcnn:
mAP: 76.78%, rank-1: 77.48%

mmdetection faster-rcnn:
mAP: 85.21%, rank-1: 85.52%

I was wondering how much does detection performance affects the mAP and rank-k metrics?

looking forward to your reply! @serend1p1ty

Generally, better detection leads to better Re-ID. We describe how much does detection performance affects the mAP in our paper SeqNet-table1
