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.
all programs start with gpiv_.

this package contains all files used by gpivtools and gpivtools-mpi, like the man pages.
