Abstract 

We propose a framework of visual attention grounded on earlier attentional and perceptual models to serve as a basis for the de- velopment of computational vision systems. The framework is build on generally established knowledge about the neural basis of human atten- tion, models developed by Briand [1][2], Itti and Koch [3][4], and Wolfe [5][6] and our own results that call for adaptations of the existing mod- els [7][8]. In this paper we concentrate on the interaction of bottom-up and top-down processes to understand the mechanisms underlying ex- ogenous 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 [7]. Secondly, we demonstrate the ability to preset the bottom-up feature maps by demonstrating the phenomenon of In- hibition of Return (IOR) with endogenous cueing, suggesting that IOR a???ects processing before focusing attention [8].
