The detectability of a sinusoidal grating was measured in a standard two-interval forced-choice experiment against backgrounds of noise gratings of the same orientation as the signal. The noise gratings were either spatially high-pass or low-pass filtered and were either unchanged in each observation interval (static) or flickering at a rate that depended on their cutoff frequency (dynamic). Spatial-frequency-selective mechanisms are inferred from the data and their characteristics shown to depend on assumptions concerning the detection process thought to follow the spatial-frequency-selective device.

  15. Stromeyer and Julesz kept the product of the square of the noise contrast and the bandwidth of their masking noise constant when changing cutoff frequencies.17 If we assume that masking is proportional to noise-contrast density, then we might adjust the data in Fig. 6 to show the contrast elevation that would have occurred had Stomeyer and Julesz kept their noise-contrast density constant. The correction steepens the low-frequency side from about 0.35-log-unit change of contrast per halving of spatial frequency to 0.52 log unit per halving. The steepening of the high-frequency side is negligible when the correction is applied on the basis of the bandwidths used by Stromeyer and Julesz.
