Running time:0.08 s
Environment:GPU @ 2.5 Ghz (Python)

Method Description:
The method tackles the association issue for long-
term tracking with the exclusive fully-exploited
motion information. We address the tracklet
embedding issue with the proposed reconstruct-to-
embed strategy based on deep graph convolutional
neural networks (GCN)

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.
