| Abstract: | A method for tracking ensembles of particle images of a digital PIV record by making use of the  minimum quadratic difference (MQD) technique is described. The similarity of this method with correlation schemes used for the evaluation of PIV is discussed. The method is exemplified with two applications that are also evaluated by auto- and cross-correlation, respectively.Receipt of a fellowship from Deutscher Akademischer Austauschdienst (DAAD) for L. C. Gui is gratefully acknowledged. |
