Figure Legend:
Schematic diagram of the generative process assumed by the estimator used in the model. The estimator assumes that
figures are drawn from one of two categories—isotropic figures (e.g., circles) or figures with a distribution of random
aspect ratios. The figure seen at any particular instance is randomly drawn from one of the two sets with probabilities p
isotropic and 1 − p isotropic. If it is drawn from the random ensemble, its aspect ratio is presumed to be drawn from the
appropriate probability distribution. The likelihood function for slant from the retinal shape information is an additive
mixture of likelihood functions computed for each of the two sets of figures, weighted by the probability that a figure is
