Epipolar Geometry from the Deformation of an Active Contour

An active contour is used to track a target in a sequence recorded by a walking robot in an unstructured scene . The deformations of the contour are analysed in order to extract the robot's egomotion, from which we compute the epipolar geometry that guides the matching between different views of the scene. The results prove that the proposed solution is a promising alternative to the prevalent techniques based on the costly computation of displacement or velocity fields [12, 14].
