Our previous study confirmed that ellipsoidal differential equations can be used to interpolate particle tracking velocimetry (PTV) measurement results. In the preset study, we deal with extensions of the equations; to time serial processing and to the detection of mismatched vectors. The performance of these algorithms is evaluated by using the flow around a rectangular cylinder and a vortex flow. Furthermore, the actual advantages of utilization of these methods are discussed by applying them to the experimental result of sudden vortex generation due to the collision of a circular cylinder with a flat wall.
