A model for perceived spatial frequency and spatial frequency discrimination.
The 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.
