Optical flow refers to an image processing technique originally developed for computer and robot vision applications. In this Letter, optical flow algorithms are utilized to obtain two-dimensional velocity fields corresponding to fluid flows. The performance of the algorithms with regard to three flows is discussed: computer-simulated suspension flow, bubble detachment from a submerged needle, and in vivo blood flow in a microvascular network. For small changes in successive images, the algorithms yield good quantitative and qualitative information about the flows. © 1995 American Institute of Physics.
