Abstract
In this paper we propose a new topology based metric for 2D vector
fields. This metric is based on the concept of feature flow
fields. We show that it incorporates both the characteristics and
the local distribution of the critical points while keeping the
computing time reasonably small even for topologically complex
vector fields. Finally, we apply the metric to track the
topological behavior in a time-dependent vector field, and to
evaluate a smoothing procedure on a noisy steady vector field.
