Inquiry regarding the data extraction

[Firdaus Ayub]

Hello Mr. William,

First of all, thank you for the free access of PIVlab, which is handy for us to do PIV. I would like to ask, is it possible to extract how much particle displaced in the interrogation window? one more thing, is it PIVlab able to visualise the correlation peak?

Thank you for the help.

Regards,
Firdaus

Dear Firdaus,

Here is some information on enabling correlation matrices:

Here is some information on correlation matrix vs. correlation map:

What do you mean by "  is it possible to extract how much particle displaced in the interrogation window"? Estimating the displacement of particles inside interrogation windows is what PIV is all about? If you do not calibrate, you get the displacement in pixel units.
