The Structure of the Optic Flow Field

  title={The Structure of the Optic Flow Field},
  author={Mads Nielsen and Ole Fogh Olsen},
The optic ow eld is deened as preserving the intensity along ow-lines. Due to singularities in the image at xed time, poles are created in the optic ow eld. In this paper we describe the generic types of ow singularities and their generic interaction over time. In a general analytic ow eld, normally the topology is characterised by the points where the ow vanish again subdivided into repellers, attractors, whirls, and combinations hereof. We point out the resemblance, but also the important… CONTINUE READING
