;Shadow Stereopsis : A . Medina Puerta demonstrated that retinal images with no parallax disparity but with different shadows are fused stereoscopically, imparting depth perception to the imaged scene.
32.
It was shown that the areas of the activity in V1 related to the disks were of unequal size, despite the fact that the retinal images were the same size.
33.
The results suggest that impairments in parsing, such as the process by which important regions are extracted from the retinal image, or difficulty in discriminating elementary visual features led to simultanagnosia.
34.
It is possible that inheritance causes abnormalities in either the flocculus or in structures that project into the flocculus to maintain stability of the retinal image of stationary or moving visual objects.
35.
If the images produced by the painter on canvas are only an illusion no more than skin deep are the retinal images that we rely on in everyday life any more trustworthy?
36.
In the case of retinal imaging, light passing out of the eye carries similar wavefront distortions, leading to an inability to resolve the microscopic structure ( cells and capillaries ) of the retina.
37.
Kepler's later theory of the retinal image ( which resolved the problem of the correspondence of points on an object and points in the eye ) built directly on the conceptual framework of Alhazen.
38.
For example, neural activity for the interaction between gaze direction and retinal image location is almost exactly multiplicative, where x represents the location of a stimulus in retinal coordinates and y represents gaze angle.
39.
According to the empirical framework, the visual system solves this problem by drawing on species and individual experience with retinal images that have signified different combinations of illuminance, reflectance, and transmittance in the past.
40.
But, as already noted, " other factors " can intervene to slightly change " ?2 " for a target forming a constant sized retinal image ( and thereby create a visual angle illusion ).
