AWS will find and fix all grammatical errors and revise text, in addition to proofreading. The slope differences Figures 4G—I are around 0.
For all plots in Figure 5the steepness of the curve changes at around 40 cpi, similar to the example shown in Figure 1. AWS handles it all!
In the present study of the Fourier spectra of text images, we therefore studied cardinal horizontal and vertical and oblique orientations separately to obtain 1d spectra, rather than radially averaging across all orientations together, as usually done when analyzing natural scenes and aesthetic images see above.
Mean radially averaged Fourier power for the images of Western graphic art Redies et al. By using these terms for different categories of images in the present study, we rely on views that are commonly held by the general public.
In the present study, curvilinear power spectra are also observed for several of the image categories for example, images of text, calligraphy, and ornamental artbut the images used by us do not evoke obvious visual discomfort in general. For the high-frequency part Figure 3Bthese image categories are about as lower or higher than those of fine art.
