TransMOT: Spatial-Temporal Graph Transformer for Multiple Object Tracking

Chu, Peng, Wang, Jiang, You, Quanzeng et al.

Understand

Tracking multiple objects in videos relies on modeling the spatial-temporal interactions of the objects.

  • In this paper, we propose a solution named TransMOT, which leverages powerful graph transformers to efficiently model the spatial and temporal interactions among the objects.
  • TransMOT effectively models the interactions of a large number of objects by arranging the trajectories of the tracked objects as a set of sparse weighted graphs, and constructing a spatial graph transformer encoder layer, a temporal transformer encoder layer, and a spatial graph transformer decoder layer based on the graphs.
  • TransMOT is not only more computationally efficient than the traditional Transformer, but it also achieves better tracking accuracy.
