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 derivatived quantities from the PIV data, like vorticity and strain. . miscelaneous 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_. |
