Reverse time order Tracking

[wenyiwangbst]

Hi, Thanks for sharing the code. When I look into the tracking module, I notice that the default score threshold for first stage tracking is 0.1 while the detection output score threshold is 0.03. So for second stage only objects between 0.03 and 0.1 are considered. However in Reverse time order tracking it only run stage two which will only consider objects between 0.03 and 0.1. Is it what the detzero tracking designed for or it's a bug which originally should use two stage tracking as well or only use stage one tracking?
