Plot of vorticity computed from estimated velocity field.<br />Velocity field is estimated from real PIV 1024*1024px images, using wavelet-based optic flow technics.<br />Vorticity map is superimposed on input images, so as to enable a visual check/comparison between estimated particles' behavior and actual one.<br />More information: http://www.irisa.fr/fluminance/team/Pierre.Derian.html
