What is PIVlab?

PIVlab is an extremely easy to use Matlab toolbox that calculates velocities in image data (movies, pictures). It uses a method called 'Particle Image Velocimetry'. Usually, this method is used to calculate velocities in fluids. But there are also many other possibilities.


  • userfriendly and GUI based PIV tool
  • multi-pass, multi-grid window deformation technique
  • import bmp/ tiff/ jpeg image pairs/ series
  • multiple image sequencing styles
  • individual image masking and region of interest
  • image pre-processing
  • two different sub-pixel estimators
  • multiple vector validation methods
  • magnitude/ vorticity/ divergence/ shear / ...
  • data smoothing, vector field highpass
  • multiple colormaps
  • streamlines
  • extensive data extraction tools
  • statistics
  • synthetic PIV image generator
  • many data export features
  • main features accessible via comand line scripting
