Which joint interactions in the human gait cycle can be used as biometric
characteristics? Most current methods on gait recognition suffer from the lack
of interpretability. We propose an interpretable feature representation of gait
sequences by the graphical Granger causal inference. Gait sequence of a person
in the standardized motion capture format, constituting a set of 3D joint
spatial trajectories, is envisaged as a causal system of joints interacting in
time. We apply the graphical Granger model (GGM) to obtain …
