Several recent model studies of visual cortex have used Bayesian
networks and their belief propagation algorithms, and successfully
explained various physiological properties. This paper shows that
a similar model can also explain another property called
border-ownership, one of contextual effects in early visual cortex
reported by Zhou et al. We show that border-ownership signals can
be interpreted as posterior joint probabilities of a low-level edge
property and a high-level figure property, and can readily be found
in a typical hierarchical Bayesian network mimicking early visual
cortex, under certain conditions. We also present the result of a
computer simulation that model neurons in our Bayesian network can
reproduce response properties qualitatively similar to physiological
data. |
