Extractions_Parameters from poly-line

[若杉栄光]

Hi, thanks for your tool.

I am Eikou Wakasugi, university student.

In extracting parameters from poly-lines, there are velocity distributions even where there are no arrows, I would like to know why?

In PIV, you correlate "interrogation areas". PIV assumes that the velocity in each interrogation area is constant. For each correlation area (e.g. 32 x 32 px), only 1 vector is shown in the centre. But this vector represents the velocity in the whole correlation area.

Thank you for taking the time to answer my question.
