Running time:0.04 s
Environment:GPU @ 1.5 Ghz (Python)

Method Description:
An online multi-object tracker designed for
occlusion handling in low-frame-rate scenarios. We
identify discontinuously visible targets by
detecting anomalies in optical flow estimation and
accordingly switch between vision cues and motion
cues.
Parameters:
See manuscript.

Detailed Results

From all 29 test sequences, our benchmark computes the HOTA tracking metrics (HOTA, DetA, AssA, DetRe, DetPr, AssRe, AssPr, LocA) [1] as well as the CLEARMOT, MT/PT/ML, identity switches, and fragmentation [2,3] metrics. The tables below show all of these metrics.
