JPIV is a complete and open source software package for 2D Particle Image Velocimetry (PIV) – an image based fluid flow measurement technology. JPIV is widely used in research for analysing all kinds of pattern movement.

• graphical user interface providing an efficient workflow and batch processing
• entirely written in Java, therefore platform independent
• highly accurate and fast because of multi-pass, multi-grid, FFT based correlation algorithmm
• ensemble correlation (correlation averaging) implemented
• complete ready for Micro-PIV and high resolution boundary flow measurements: rectangular evaluation areas possible, single pixel resolution ensemble evaluation implemented
• image preprocessing
• outlier detection
• masking
• calculation of various statistical information as well as some derivatives like vorticity
• 3d velocity field reconstruction from 2d planes in incompressible flows
• publication ready vector plots and export in various vector graphics and pixel formats
• batch processing
• arbitrary velocity profile extraction
• region of interest
• synthetic image generation
• extension and automation by user scripts

Prerequisite: A Java Runtime Environment (JRE).

1. Download the zip-archive.
2. Extract it to your hard disc.
3. Open a terminal and cd into the new directory.
4. Execute java -jar JPIV.jar.
