OSIV Description

Open source image velocimetry 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.OSIV was designed with modularity and efficiency as high priorities. As such, OSIV supports several algorithms to perform each of the steps involved in PIV: cross correlation, peak interpolation and pre-processing. Each of these algorithms has been extensively profiled and optimized. OSIV has the following correlation algorithms:· Direct Least Squares· Fast Direct Least Squares· Direct Cross-Correlation· Fast Direct Cross-Correlation· Fourier Cross-Correlation· Fourier Least Squares· Iterative Fourier Correlation Here are some key features of "OSIV": · Five image pre-processing algorithms · Four peak interpolation algorithms · Global pre-shifting for all algorithms · Sophisticated synthetic image generation · Arbitrary window size for all algorithms · Versatile batch processing of sequences · Publication-quality graphics generation
