An analysis of extant literature reveals a large body of experimental evidence supporting the concept that the human visual system performs a two-dimensional harmonic analysis of visual stimuli. It also reveals a smaller body of evidence that seems to contradict this concept. Experiments performed propose a resolution of these apparent contradictions, and show how existing concepts must be slightly modified to include changes in the kind of harmonic analysis performed. Three kinds of analysis, representing increasingly fine spatial-frequency resolution, seem to quantify human performance at many form-perception tasks the kind of analysis performed depends on the task. A single plot showing the masking effect of one spatial frequency on another promises great utility in target acquisition and detection studies camouflage designs, and designs for optimal manmachine interfaces.
