Abstract
Efficient and well adapted algorithms are necessary to analyse the large number of vector fields generated when observing time dependent flow fields. This paper discusses several possibilities of vortex detection and characterization from two-dimensional instantaneous vector fields like those obtained by means of the particle image velocimetry (PIV) technique.Keywords
