Good afternoon,

I am writing to kindly ask, if possible:

1.To have more information on the extraction of streamlines in PIVLab once properly calculated velocity vectors;

2.If a metric has been introduced (or is recommended) for the evaluation of the accuracy of the interpolated velocity vectors.

Thank you in advance for your attention

Hi, streamlines are calculated with this function:

The accuracy of interpolated vectors (of the interpolation schemes) was tested on my thesis, chapter 2:
