The coherent tubular vortices, which exist ubiquitously in turbulent flows and play central roles in turbulence dynamics, are visualized by the low-pressure vortices. Since many vortices move about randomly in a turbulent flow, it is not easy to track, by the naked eye, a particular vortex. Here we propose an automatic tracking scheme for low-pressure vortices which may be useful in investigating the dynamics and life history of individual vortices.
