This video shows velocity vectors estimated from a real PIV sequence, using the under-development wavelet-based estimator from Fluminance team.
Velocity vectors are here superimposed on original input frames, slightly colord in orange to improve visualization. Laminar velocity field (heavy upward translation) has been substracted, so that turbulent structures are more visible.
100 sucessive frames have been used, each pair of images being processed indendently (no memory).
