Particle Cluster Tracking Algorithm in Particle Image Velocimetry.
JSME International Journal Series B, 1998 The cross-correlation tracking technique is widely used to analyze image data, in particle image velocimetry(PIV). The technique assumes that the fluid motion, within small regions of the flow field, is parallel over short time intervals. However, actual flow fields may have some distorted motion, such as rotation, shear and expansion.

Tomographic X-ray particle tracking velocimetry
, 2022 Abstract: We investigate the feasibility of in-laboratory tomographic X-ray particle tracking velocimetry (TXPTV) and consider creeping flows with nearly density matched flow tracers. Specifically, in these proof-of-concept experiments we examined a Poiseuille flow, flow through porous media and a multiphase flow with a Taylor bubble.
