The spherical retina a conformal geometric algebra model for human like vision

In this paper we propose a conformal model for human like vision. In our model the two views are fused in an extended 3D horopter concept. The inverse transformation of the horopter spheres and Poncelet points leads remarkably to a 3D log-polar representation of the visual space. This representation is quite effective for processing the visual space information. We believe that this model is very suitable for building a powerful binocular head for humanoids.
