Abstract
We present an analytical ideal observer model to predict discrimination thresholds for stimuli that are processed by arrays of noise-perturbed receptors that have smooth and overlapping tuning functions. We show that hyperacuity phenomena are natural properties of these systems. A comparison of thresholds for a number of discrimination tasks allows a psychophysically derived estimate of parameters of the receptor array involved. We note the consistency of this scheme with data from a number of visual subfields.
