A Context-Based Model of Attention

d abstract)1 Niek Bergboer Eric Postma Jaap van den Herik Institute for Knowledge and Agent Technology, Universiteit Maastricht, P.O. Box 616, 6200 MD Maastricht It is well known that natural visual systems rely on attentional mechanisms that select and process relevant objects in an efficient way. Similarly, artificial visual systems need attentional-selection mechanisms to reduce the computational burden of processing entire images. So, their aim is to focus on the parts containing the object of interest. In the domain of natural vision the locus of selection has been debated for many years (see [1] for an overview). The two extreme views are (1) that selection takes place at an early stage of visual processing (i.e., early selection), and (2) that it takes place at a late stage (i.e., late selection). In early selection, attention is guided by conspicuous changes in elementary features, such as colour, texture, or spatial frequency. Models of early selection contain so-called sali...
