gpiv

GUI program for Particle Image Velocimetry

Gpiv is a Graphic User Interface program using the GTK/GNOME libraries for Particle Image Velocimetry (PIV). The program gives a quick overview of the parameter settings of the processes and allows to change them easy, running the processes, individually or in a chain, visualizes and displays the results. The processes that may be invoked by Gpiv are: Image processing: typical image manipulations that might be needed for PIV interrogation. Image interrogation, resulting into estimators of particle image displacements. Data validation to test on outliers, peak-locking effect and velocity gradients over the interrogation area's. Data post-processing: data manipulation, spatial and time scaling to obtain a velocity field from the PIV data, calculation of spatial averages, vorticity and strain.

This is the parallelized version using Message Passing Interface to be used on a (Beowulf) cluster.
