Webb14 feb. 2024 · Abstract. For the reliable estimation of velocity vector fields by means of particle image velocimetry (PIV), the cross-correlation functions calculated from the … Webb18 dec. 2024 · So rather than studying each particle separately or the entire image as a whole, we divide the image into smaller windows and relate these windows with the image taken at the next instant and get the displacement. Now, we do the same thing for the other windows as well. That’s the basic logic behind the cross-correlation tool. Cite As
