Dear Dr William,
I have a little problem understanding which searching area we use in PIVlab. For my thesis I use various PIV software and in the others we can choose a searching area.
After reading the documents about PIVlab, I understand that for the DCC the searching area is always 2x the interrogation area. and for the FFT, searching area = interrogation area ? and the "step" is the spacing between vectors ?
is this correct or have I misunderstood ?
