command line programs for Particle Image Velocimetry - MPI version

A collection of programs for images that are generated
during a Particle Image Velocimetry (PIV) experiment. This is a
technique to obtain the velocity field of a fluid flow quantitatively
and is performed by tracking tracer particles that have been seeded
to a fluid. The technique is also applied for observing deformations
at surfaces of (solid) bodies. The package contains:

an image processing program for typical filtering and manipulation
routines that may be convenient for PIV.

an image interrogation program resulting into estimators of particle
image displacements.

validation programs to test on outliers, peak-locking effect and
velocity gradients.

post-processing programs for data manipulation (flipping, rotation
etc), spatial and time scaling, calculation of spatial averages and
derivative quantities from the PIV data, like vorticity and strain.

miscellaneous programs and scripts to perform image format conversion,
batch-processing, pipeline processing (image evaluation, validation and
post-processing at once), calculation of time averages from a series
of PIV data sets, data-visualization and data-manipulation.

This package contains the MPI-parallelized programs for use on
a (Beowulf) cluster. All programs start with gpiv_.
