What is visible across the visual field?
Andrew Haun
Abstract
In this paper I use a detailed model of human spatial vision to estimate the visibility of some perceptual properties across the visual field, including aspects of colorfulness, sharpness, and blurriness. The model is constructed to reproduce several patterns of human contrast sensitivity, functions of contrast, scale and retinal eccentricity. I apply the model to colorful, complex natural scenes, and estimate the degree to which color and edge information are present in the model’s representation of the scenes. I find that, aside from the intrinsic drift in the spatial scale of the representation, there are not large qualitative differences between foveal and peripheral representations of ‘colorfulness’ and ‘sharpness’.
