PIVlab is a GUI based particle image velocimetry (PIV) software. It does not only calculate the velocity distribution within particle image pairs, but can also be used to derive, display and export multiple parameters of the flow pattern. A user-friendly graphical user interface (GUI) with the ability to control a PIV camera and a laser makes PIV data acquisition and data post-processing fast and efficient.

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.
