Environment:4 cores @ 3.0 Ghz (Python)

Method Description:
A framework based on dynamic undirected graphs that
represent the data association problem over multiple
timesteps, and a message passing graph neural
network (GNN) that operates on these graphs to
produce the desired likelihood for every association
therein. We only use the 2D detection box location
and score as the descriptor for each object
instance.
Parameters:
N/A

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.
