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.
标记的空间频率通道的响应被组合起来以生成感知空间频率的指标。当在对数-对数坐标上绘制时,空间频率辨别阈值显示出与该指标相对于空间频率的函数斜率呈反比关系。
