• Resumen

  • In this paper we present a novel technique to implement a complex visual behaviour: to look for where I am. The method is based on an active vision system which allows us to build real-time applications. To define this behaviour, visual scanning is used. That is: (i) a focus of attention mechanism which selects the most important visual areas to be analysed, (ii) an iconic representation based on gaussian filters (i.e. pattern matching), (iii) a dimensionality reduction criteria that allows us to reduce the complexity of the pattern matching process, and (iv) a scanning strategy. This implementation shows how complex information processing tasks can be solved by using active visual behaviour based on simple mechanisms.
