The velocity gradient range accessed with the application of a relative window deformation (linear approximation) is significantly enlarged, as confirmed in the experimental results. Moreover, peak-locking effects do not affect the method in practice. The assessment of performance through synthetic PIV images shows that a remarkable improvement can be obtained in terms of precision and dynamic range. The performances of the method are analysed and compared with the conventional cross correlation with and without the effect of a window discrete offset. JPIV is a complete, open source, and platform independent software for 2D Particle Image Velocimetry (PIV). In addition, progressive grid refinement is applied in order to maximise the spatial resolution. On the basis of an iterative prediction of the tracers motion, window offset and deformation are applied, accounting for the local deformation of the fluid continuum. The method is based on cross-correlation, enhancing the matching performances by means of a relative transformation between the interrogation areas. Particle image velocimetry (PIV) is an effective measurement method used in studies on modern fluid mechanics and can obtain motion vectors by capturing the particle motion in images (Raffel et al., 1998). It can be an extremely powerful way to capture real life (in quotes due to the errors and. PIV, or Particle Image Velocimetry, is a method of experimental flow visualization that uses seeding particles and some form of camera or optics to measure 2- or 3-dimensional vector fields.
