A Demonstration of the Visual Importance and Flexibility of Spatial-Frequency Amplitude and Phase
Explore this paper's citation graph
Summary
To establish how little information the human visual system requires for recognition, common objects were digitally manipulated in the Fourier domain to demonstrate that it is not only possible, but also quite efficient, for a (biological) visual system to exist with very few phase relationships among the component spatial frequencies of the (retinal) image.
