Vision and the optic flow field

The Structure of the Optic Flow Field

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,...

Insect Vision: Controlling Actions through Optic Flow

Insects depend upon optic flow to supply much of their information about the three-dimensional structure of the world. Many insects use translational flow to measure the distance of objects from themselves. A recent study has provided new insights into the way Drosophila use optic flow to pick out a close target to approach.

Intermediate Flow Field Filtering in Energy Based Optic Flow Computations

The Euler-Lagrange framework and splitting based methods are among the most popular approaches to solve variational optic flow problems. These methods are commonly embedded in a coarse-to-fine strategy to be able to handle large displacements. While the use of a denoising filter inbetween the warping is an important tool for splitting based approaches, such a practice is rather uncommon for the...
