我个人觉得如果想要提升fps的话,可以结合光流法(optical flow)的方法来减少detection次数。这个是在detection in video里面用的比较多的,比较经典的方法有CVPR’18的
Toward High Performance Video Object Detection (PDF:http://openaccess.thecvf.com/content_cvpr_2018/papers/Zhu_Towards_High_Performance_CVPR_2018_paper.pdf 中文解析:https://zhuanlan.zhihu.com/p/37068429)
。这个工作相当于直观上减少你问题里的detection次数,但是本身光流法就是一种追踪物体的方法,那么使用光流法生成的bounding box本身就应该带有前一帧的id信息。所以这种方法也可以减少了reid bounding box的次数。他们有开源的code,你可以测试一下
