Abstract

The paper describes a hybrid method for estimating flow-velocity vector fields from Particle Image Velocimetry (PIV) images that combines a cross-correlation technique with a multiresolution estimation based on optical flow with the aim of obtaining the highest possible spatial resolution. The method offers the possibility to determine one vector per seeding particle. The manuscript examines accuracy of the estimates compared to other known methods using various standard test images. Experimental results are also presented.
