Particle Image Velocimetry for Matlab, official repository

PIVlab - particle image velocimetry (PIV) tool with GUI

PIVlab is a graphical user interface (GUI) based particle image velocimetry (PIV) software. It can be used to control OPTOLUTION's lasers, cameras and synchronizers, and of course it calculates the velocity distribution within imported (or captured) particle image pairs. It can also be used to derive, display and export multiple parameters of the flow pattern. The simple, GUI makes PIV data acquisition and data post-processing fast and efficient.

PIVlab comes with it's own unique hardware: Pulsed lasers, LEDs, synchronizers and cameras are available here: Optolution.com

We would like to acknowledge Uri Shavit, Roi Gurka & Alex Liberzon for sharing their code for 3-point Gaussian sub-pixel estimation. Thanks to Nima Bigdely Shamlo for allowing me to include the LIC function. Thanks to Raffel et al. for writing the book "Particle Image Velocimetry, A Practical Guide", which was a very good help. Thanks to the thousands of publications that use PIVlab for research!
