2.1 INTRODUCTION

Biological vision is foveated, highly goal oriented and task dependent. This observation, which is rather clear if we trace the behavior of practically every vertebrate, is now being taken seriously into consideration by the computer vision community. This is evident from recent work on active vision systems and heads (Clark and Ferrier, 1988; Brunnstrome et al., 1992; Crowley, 1991; Rimey and Brown, 1992) and general active vision concepts and algorithms (Aloimonos et al., 1987; Bajcsy, 1988; Aboot and Ahuja, 1988; Ballard, 1990; Culhane and Tsotsos, 1992). One of the fundamental ...
