abstract     : In this paper we discuss generalizations of instantaneous,
               local vortex criteria. We incorporate information on spatial
               context and temporal development into the detection process.
               The presented method is generic in so far that it can extend
               any given Eulerian criterion to take the Lagrangian approach
               into account. Furthermore, we present a visual aid to
               understand and steer the feature extraction process. We show
               that the delocalized detectors are able to distinguish
               between connected vortices and help understanding regions of
               multiple interacting vortex structures. The delocalized
               detectors extract smoother structures and reduce noise in
               the vortex detection result
