Abstract(s)
Most biological approaches to disparity extraction rely on
the disparity energy model (DEM). In this paper we present an alternative
approach which can complement the DEM model. This approach
is based on the multiscale coding of lines and edges, because surface
structures are composed of lines and edges and contours of objects often
cause edges against their background. We show that the line/edge approach
can be used to create a 3D wireframe representation of a scene
and the objects therein. It can also significantly improve the accuracy of
the DEM model, such that our biological models can compete with some
state-of-the-art algorithms from computer vision.
