Psychophysical test of a stereo coding theory --- how ocularity
depends on the scene statistics.
Zhaoping Li
A theory of efficient coding in stereo vision predicts that a cortical
cell is more likely binocular when it is selective to near horizontal
rather than near vertical orientations. This prediction had not been
experimentally investigated. A subsequent physiological test of this
prediction supports the theory. Here we report the results from a
visual psychophysics experiment which is designed to test the
prediction. The experimental results agree with the prediction, and
in addition show how the stereo coding depends on the statistics of
the visual inputs.
