As an extension of flow visualization, particle tracking velocimetry (PTV) determines particles' trajectories and velocities by capturing and analyzing each particle image to locate its center and connecting image tracks (possibly multiple exposures) (Adrian 1996a), therefore offering an approach to investigate Lagrangian characteristics of fluid motion (Agui and Jimenez 1987; Virant and Dracos 1997; Cenedese and Querzoli 1997).
