Abstract

Optical Fourier analysis of photographic samples of three visual environments—indoor carpentered, outdoor carpentered, and pastoral—showed that in the 1–25 c/deg spatial frequency range, carpentered environments contained more information in horizontal (H) and vertical (V) orientations. However, in the 5–25 c/deg range the V orientation dominated, and the pastoral environment had the greatest anisotropy. Thus, a spatial-frequency-specific influence of carpentered environments on anisotropic acuity, which favors both H and V at higher frequencies, is not substantiated.
