Features of the second-order visual filters sensitive to the spatial frequency modulations

M. B. Miftakhova, V. V Babenko

چکیده

We investigated selectivity of 2 nd order visual filters sensitive to the spatial frequency (SF) modulations to orientation and to SF of modulation. We carried out psychophysical experiment using masking paradigm. It was found that 2 nd order filters are selective to SF of modulation (with bandwidth +1.5 octaves), and do not show any selectivity to orientation of modulation. We suppose receptive fields of 2 nd order mechanisms have concentric form.

    In this paper the problem of the frequency estimation of a sinusoid embedded in white noise is considered. The approach used herein is the minimization of the sample variance of the output of constrained notch filters fed by the noisy sinusoid. In particular, this paper focuses o

    It has been shown that the perception of contrast-defined motion (i.e., a second-order stimulus) at high temporal frequencies cannot be explained solely by global distortion products (i.e., luminance artifacts due to preprocessing nonlinearities) processed by the first-order syst

    Human observers are able to localize the relative position of objects defined by Gaussian variations in either luminance (1st order) or contrast (2nd order). However, positional sensitivity is significantly poorer for 2nd- than for 1st-order stimuli. These judgments require the v
