OSIV is a program written to perform cross-correlation analysis of particle image velocimetry (PIV) images. The program was designed to be both very modular and quite efficient. It incorporates most of the tried-and-true algorithms and some of the more recent additions to the PIV toolkit. Importantly, OSIV is released open source so that users may contribute back to the project.

A beta version of the program is available for download, and users are encouraged to download and experiment with OSIV. Presently this program may be used only through a command line interface. When the core code is stable, we will begin the development of a graphical interface.
