One spatial filter limits speed of detecting low and middle frequency gratings
Reaction times for detecting sinusoidal gratings depend jointly on grating contrast and spatial frequency. We examine whether the effect of spatial frequency results from low-pass filtering in a single channel or reflects processing of different frequencies by two or more different processing streams. Observers performed a speeded two-alternative spatial forced-choice detection. Errors and reac...
متن کاملSpeed, spatial-frequency, and temporal-frequency comparisons in luminance and colour gratings.
The perceived speed, temporal frequency, and spatial frequency of matched colour and luminance gratings were compared in separate experiments. The large factor by which colour gratings are perceived to be slower moving than matched luminance gratings cannot be explained by systematic differences in the perceived spatial frequency or in the perceived temporal frequency of the two types of grating.
متن کاملLow Quality Fingerprint Image Using Spatial and Frequency Domain Filter
The Biometrics indicators, Fingerprints are one of the highest levels of reliability and have been extensively used by forensic experts in criminal investigations. Anyway the performance of these techniques relies heavily on the quality of input fingerprint. But already existing STFT (short-time Fourier transform) analysis is not much perfect and best suit, to recover these unrecoverable region...
متن کاملDiscriminability of suprathreshold compound spatial frequency gratings.
We have investigated the detectability of small contrast changes in compound suprathreshold gratings, containing two sinusoidal components. We examined the relationship between the detectability of changes in each of the components alone and the detectability of changes in the two components together. It was found that for the pairs of spatial frequencies 1 and 9 c/deg there is a square law sum...
متن کاملApplications of the normal-incidence rotating-sample ellipsometer to high- and low-spatial-frequency gratings.
The normal-incidence rotating-sample ellipsometer is an instrument that can be used to characterize grating surfaces from the measured ratio ρof complex reflection coefficients r(y)/r(x) of light polarized perpendicular and parallel to the grating groove direction. Experimental results at different wavelengths for different gratings with spatial frequencies from 150 to 5880 grooves/mm are prese...
