Understanding the interactions of bottom-up and top-down visual attention for the development of a humanoid robot system

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

We propose a framework of visual attention grounded on
earlier attentional and perceptual models to serve as a basis for the
development of a social robot. The framework is build on generally es-
tablished knowledge about the neural basis of human attention, models
developed by Briand, Itti & Koch, & Wolfe and our own
results that call for adaptations of the existing models. In this paper
we concentrate on the interaction of bottom-up and top-down processes
to understand the mechanisms underlying exogenous and endogenous
attention. Two series of studies are reported to support the proposed
adaptation of the earlier models. First, we claim that the visual feature
binding is a common process for exogenous and endogenous attention
. Secondly, we demonstrate the ability to preset the bottom-up fea-
ture maps by demonstrating the phenomenon of Inhibition of Return
(IOR) with endogenous cueing, suggesting that IOR aspects processing
before focusing attention.
