Abstract:

Marr and Poggio have proposed in their theory of visual information processing that zero-crossings are the most important primitives obtained in the visual primary processing. This is consistent with the physiological observations such as two Gauss like receptive fields, lateral inhibition phenomena and so on But, there is still lack of psycholophysical evidence about this. We have used the random-dot stereograms with a variety of densities and contrast noises to observe the anti-noises characteristics of stereopsis. Our observations are favourable to the "edge" (zero-crossing) as the primitives. In this paper, the experiment results are reported and discussed.
