Extending the kinematic theory of rapid movements with new primitives. (arXiv:2401.16519v1 [cs.CV])
cs.CV updates on arXiv.org arxiv.org
The Kinematic Theory of rapid movements, and its associated Sigma-Lognormal,
model 2D spatiotemporal trajectories. It is constructed mainly as a temporal
overlap of curves between virtual target points. Specifically, it uses an arc
and a lognormal as primitives for the representation of the trajectory and
velocity, respectively. This paper proposes developing this model, in what we
call the Kinematic Theory Transform, which establishes a mathematical framework
that allows further primitives to be used. Mainly, we evaluate Euler curves to
