Olshausen BA, Anderson CH, Van Essen DC (1995). A multiscale routing circuit
for forming size- and position-invariant object representations. The
Journal of Computational Neuroscience, 2, 45-62.
We describe a neural model for forming size- and position-invariant representations
of visual objects. The model is based on a previously proposed dynamic
routing circuit (Olshausen et al., 1993, J Neurosci, 13: 4700-4719) that
remaps selected portions of an input array into an object-centered reference
frame. Here, we show how a multiscale representation may be incorporated
at the input stage of the model, and we describe the control architecture
and dynamics for a hierarchical, multistage routing circuit. Specific neurobiological
substrates and mechanisms for the model are proposed, and a number of testable
predictions are described.
