Running head: FACE PERCEPTION AND SPATIAL FREQUENCIES
The aim of this article is to reinterpret the results obtained from the research analyzing the role played by spatial frequencies in face perception. Two main working lines have been explored in this body of research: (a) the critical bandwidth of spatial frequencies that allows face recognition to take place (the masking approach) and (b) the role played by different spatial frequencies while ...
متن کاملHigh Spatial Frequencies Are More Dynamic Than Low Spatial Frequencies In Cardiac Motion
Introduction Effective strategies for sparse sampling of kt-space are important for fast dynamic imaging. Following observations in early landmark papers [1-3] the temporal sampling rate of each k-space view is often linked to the signal energy represented by that view in k-space for a certain class of images, in general considering only the spatial or spatiotemporal spectrum of the entire imag...
متن کاملHigh and low spatial frequencies in website evaluations.
Which features of websites are important for users' perceptions regarding aesthetics or usability? This study investigates how evaluations of aesthetic appeal and usability depend on high vs. low spatial frequencies. High spatial frequencies convey information on fine details, whereas low spatial frequencies convey information about the global layout. Participants rated aesthetic appeal and usa...
متن کاملPigeons use high spatial frequencies when memorizing pictures.
The ability of animals to visually memorize and categorize a large number of pictures is well established. Determining the kinds of information animals use to accomplish these goals has been more difficult. This experiment examined the contribution of spatial frequency information to picture memorization by pigeons. A series of grayscale pictures were notch-filtered to eliminate different porti...
متن کاملLow and High Spatial Frequencies Are Most Useful for Drawing
What perceptual information do artists use to accurately render what they see? To answer this question, we investigated the utility of low, middle, and high spatial frequency bands for drawing. Untrained artists drew portraits from four spatial frequency bands (unfiltered, low, middle, and high). Raters judged the accuracy of those drawings compared to images of either the same or an unfiltered...
