My name is Eugene, Civil Engineer at the National Technical University of Athens (NTUA), Greece, and I am currently PhD student applying PIV in the study of incompressible fluids regarding rapidly varied free surface flows.
I find extremely interesting the PIVlab code that you developed during your research.
I would like to ask you what is the ''Step'' in the FFT Window Deformation Algorithm?
If I am right is Step the maximum offset (displacement) between the two interrogation windows in the FFT algorithm in order to avoid the aliasing of correlation peaks?
I am looking forward for your reply.
Thank you very much.
