Our Particle Image Velocimetry (PIV) tool, prana, implements a Robust Phase Correlation kernel for PIV analysis, and now includes Particle Tracking Velocimetry and sizing tools. But his code is light-years nicer and faster than mine was. It's main benefit stems from the fact that it removes the "derivative kick" caused by an abrupt change in set point and thus is useful for applications where set point tracking is most important (rather than fast disturbance rejection). The PIV aspect of this work comes from work done at our group, the Plasma Sciences Laboratory at Auburn University. White & W. OSIF. By taking two closely spaced images or ‘snapshots’ of the species, and using correlation algorithms, it is possible to build up 2D and 3D dynamic flow maps [1].
