Marr and Poggio (1979) Suggested That the Visual System Determines

Marr and Poggio (1979) suggested that the visual system determines the correspondences in the two retinal images, and thus it is possible to compute the binocular disparities by making two simple and quite reasonable assumptions about the world when matching features in the left and right retinal images. Here, one of these assumptions states that:

A) if surface variations are fairly regular in size and spacing, the retinal image size of these equal-size features decreases as their distance increases.
B) each feature in one retinal image will match three or more features in the other retinal image.
C) almost every point in the field of view is surrounded by points at different depths.
D) each feature in one retinal image will match only one feature in the other retinal image.
