ABSTRACT
Stereoacuity depends not only on the carrier frequency of Gabor stimuli, but also upon their size. To determine if this is also the case at large disparities, we have measured the upper limit for stereopsis, "Dmax", and assessed its dependence on carrier frequency and overall envelope size. The results differ markedly from the stereoacuity data. Dmax for stereopsis is primarily dependent on the size of the envelope of the Gabor patch, and is relatively independent of its carrier frequency. These results support the proposition that stereopsis is achieved at large disparities by way of non-linear processing (envelope extraction).
