Have a significantly lower bias and RMS error than non-particle images. Linear correlation and repeated correlation increase the robustness and decrease biasĪnd root-mean-square (RMS) error of the displacement estimates. Using experimental images and synthetic images of particle and non-particle textures. The benefit of these improvements is evaluated Paper presents several improvements that were implemented in PIVlab, enhancing the Used for flow analyses where a thin laser sheet illuminates suspended particles in theįluid, but also for other moving textures, like cell migration or ultrasonic images. The most probable displacement within each interrogation area. The resulting correlation matrix is used to estimate Input images are divided into sub-images (interrogation areas), and for each of these,Ī cross-correlation is performed.
