Method Description:
First we build tracklets by calculating a
segmentation mask for each detection and linking
these over time using optical flow. We then fuse
these tracklets into 3D object reconstuctions using
depth and ego motion estimates. These 3D
reconstructions are then used to estimate the 3D
motion of objects, which is used to merge tracklets
into long-term tracks, bridging occlusion gaps of up
to 20 frames. This also allows us to fill in missing

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.
