[Principle of uncertainty in vision].

Abstract

When investigating the dependence of the bandwidth of the spatial frequency characteristic (delta F) of the receptive fields of the cat striate cortex on the size (D) of the receptive field it was shown that delta FD = 1.2. Thus in the system of elements performing the processing of information in the visual cortex the inaccuracy of the signal representation in the spatial frequency and in space is related by an uncertainty principle. The size of the constant evidences that the weighting functions of elements are sinusoids or cosinusoids modulated by squarewave impulse rather than by the Gabor elements. The performing of uncertainty principle and the size of the constant are arguments in favour of the hypothesis that the receptive fields of the visual cortex organize a quasilinear basis.
