Abstract:

We present a model for the processing of positional information in the human visual system, with particular emphasis on visual tasks that involve the measurement of spatial separation. The model is in many respects a radical departure from current thinking about problems in vision. Of particular note is the fundamental significance we attach to the retinal photoreceptor lattice, considered as a two-dimensional spatial sampling system. Mechanisms of neural interpolation are discussed and hyperacuity is a natural consequence of the model. Major concerns which we do not address are questions of temporal dependence and the integration of binocular information. We refer to the model as the scaled lattice model.
