A model for perceived spatial frequency and spatial frequency discrimination
Vision Research, 1991The responses of labelled spatial frequency channels are combined to generate an index of perceived spatial frequency. Spatial frequency discrimination thresholds are shown to be inversely related to the slope of the function of the index vs spatial frequency, when it is plotted on log-log co-ordinates.

Joint spatial/spatial-frequency representation
Signal Processing, 1988Abstract In this paper, we first consider the motivations for current interest in the application of conjoint signal representations to problems in visual processing and form representation. The issue of conjoint resolution is then discussed, especially as it pertains to joint energy and pseudo-energy signal representations.

Spatial-frequency adaptation affects spatial-probability summation
Journal of the Optical Society of America, 1983The effects of spatial-frequency adaptation on spatial-probability summation were investigated by two techniques: the measurement of the dependence of cosine grating sensitivity on the number of cycles presented and the determination of the frequency-of-seeing curve for a cosine grating.

Spatial and spatial-frequency primitives in spatial-interval discrimination
Journal of the Optical Society of America A, 1985Thresholds for spatial-interval discrimination were determined under conditions designed to introduce randomness in the spatial-frequency content of the stimuli from trial to trial. Neither a random scaling of the display nor the addition of flanking bars at varying distances affected the observer's ability to judge the relative interval between pairs ...

Interactions between spatial frequency channels
Vision Research, 1978Abstract The sensitivities for sinusoidal gratings of various spatial frequencies were determined by a two-alternative forced-choice technique. The effects of the simultaneous presence of a grating of 4.25 c/deg on sensitivity were examined. The effects of prolonged adaptation to the same grating were also examined.

Perception time and spatial frequency
Vision Research, 1976Abstract The time of detection of a feature of square-wave gratings (orientation or a small difference in spatial frequency between two adjacent gratings) was studied as a function of stimulus spatial frequency. The relative perception time was measured by the reaction time method or by the method of masking.

Spatial frequency in speckle metrology
Applied Optics, 1990Speckle metrology, as applied to whole field displacement measurements, has been reviewed from the point of view of the relevant frequency domain. It is shown that spatial frequency defines sensitivity and resolution for both pointwise and whole field analysis.
