Our modeling will be critically tested on an autonomously learning humanoid robot, equipped with binocular foveal vision
and human-like audition.
The emphasis on foveal vision
is known as cortical magnification or M-scaling, (9-10) a concept that is demonstrated in Figure 1, where a physically small area of retina (the fovea) is represented on a much greater scale within the primary visual cortex.
Since, currently it is an all or nothing consideration of cones and foveal vision
, on the surface, it sounds like a good thing.
The hypothesis that, due to visual saliency, the smiling mouth radiates to adjacent facial regions implies, first, that the smile would be particularly resistant to visual acuity degradation when it appears outside of foveal vision
Panchuk and Vickers (2009) suggested that determining the extent to which participants picked-up peripheral target information was not possible because the eye-tracking technology is limited to measuring foveal vision
Excessive tension of those muscles perpetuates an elongated shape of the eyeballs, interfering with natural focal length and disturbing optimal foveal vision
, a very common characteristic of the myopic eye.
An eye fixation encompasses a high-acuity foveal vision
area of about 2[degrees] (Wandell, 1995).
These inequalities are propagated further along the visual system, with relatively larger regions of lateral geniculate nucleus (LGN) and visual cortex being devoted to foveal vision
than to peripheral vision which is named cortical magnification or scaling factor (Connolly & Van Essen, 1984; Daniel & Whitteridge, 1961; Hubel & Wiesel, 1974; for a review see Battista, Kalloniatis, & Metha, 2005).
Because Mitchell used mainly his foveal vision
to observe vdB 142's central cavity, it appeared dark.
This typical reading process is disrupted when foveal vision
is lost because of macular disease.
Accordingly, engineering psychologists have argued that conventional aircraft navigation instruments are relatively ineffective because they are restricted to foveal vision
and thus ignore the usefulness of the visual periphery (Wickens & Hollands, 2000).
In combination with new image processing concepts such as foveal vision
which offer 1,000:1 data reduction benefits, rapid advances in IR sensor performance capabilities will occur over the next few years.
