SANTOS, Natanael Antonio dos and SIMAS, Maria Lúcia de Bustamante. Visual processing of form: linear system analysis and some psychophysical paradigms. Psicol. Reflex. Crit. [online]. 2002, vol.15, n.3, pp. 529-536. ISSN 1678-7153. http://dx.doi.org/10.1590/S0102-79722002000300007.
The goal of this work is to discuss some basic aspects of Fourier analysis as a tool to be used in the approach of multiple channels of spatial frequencies on the study of visual processing of form. Some of the psychophysical paradigms more frequently used to characterize response of the human visual system to spatial frequency filter of narrow-band. The linear system analysis and some psychophysical paradigms have contributed to theoretical development of perception and of the visual processing of form.
Keywords : Visual processing of form; Fourier analysis; psychophysical paradigm; spatial filter; spatial frequency.
