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.
GPIV is a graphic user interface for analyzing images obtained from a fluid flow that has been seeded with tracer particles by the so-called Particle Image Velocimetry technique. It is meant to have a quick overview of the parameters of all piv processes, easily changing them, running the processes and visualizing their results in an interactive way. It uses LIBGPIV, which contains the main routi more»
This is the gpiv ptogram with MPI enabled. It uses gpiv_rr from the gpivtools-mpi packages for image interrogation. Hence, the progress in the progress bar is not working, but the interrogation processing can be monitored when gpiv is launched from the command line. The Data Acquisition (DAC) feature, i.e. the triggering of light sources (mostly Nd-YAGG lasers) with a camara and the recording o more»
