Observer translation relative to the world creates image flow that expands from the observer's direction of translation (heading) from which the observer can recover heading direction. Yet, the image flow is often more complex, depending on rotation of the eye, scene layout and translation velocity. A number of models [1-4] have been proposed on how the(More)
Any computation of metric surface structure from horizontal disparities depends on the viewing geometry, and analysing this dependence allows us to narrow down the choice of viable schemes. For example, all depth-based or slant-based schemes (i.e. nearly all existing models) are found to be unrealistically sensitive to natural errors in vergence.(More)
It is a useful competence to see motion relative to the head or to the external world, although those quantities are not directly given on the retina. The same holds for judgement of the shape of an object. We argue that the required transformations can be and are done independent of the associated direction transformations. This creates perceptual channels(More)
