This paper addresses the problem of symmetr ical 2D flow visualization and presents solutions to compute a vector field from a flow image. Based on these solutions new, interactions mechanisms are developed which make visual corrections of 2D vector fields possible. These mechanisms permit an image -based interaction with some features of the vector field: vectors, streamlines, and critical points.
