Stability, capacity, and statistical dynamics of second-order bidirectional associative memory

Psychophysical representations built by Gabor visual chan-nels described in complex analytic form are shown to be related to thewavelet transform of visual stimuli under empirically plausible bandwidthconstraints. Analysis of the psychophysical wavelet representations ofone-dimensional stimuli eliciting some visual contrast illusions (Machbands and the Craik-Cornsweet-O’Brien illusion) reveals that qualitativeaspects of the selective appearance of these illusions can be explained asa natural consequence of the functional characteristics of early visualprocessing.
