Stable Feature Flow Fields [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2011
Feature Flow Fields are a well-accepted approach for extracting and tracking features. In particular, they are often used to track critical points in time-dependent vector fields and to extract and track vortex core lines. The general idea is to extract the feature or its temporal evolution using a stream line integration in a derived vector field-the ...
