However, with a limited number of cameras viewing a scene, the two objectives are contradictory. This chapter is dedicated to active vision systems, trying to achieve a trade-off between these two aims and examining the use of high-level reasoning in such scenarios. The chapter starts by introducing different approaches to active cameras configurations. Later, a single active camera system to track a moving object is developed, offering the reader first-hand understanding of the issues involved. Another section discusses practical considerations in building an active vision platform, taking as an example a multi-camera system developed for a European project. The last section of the chapter reflects upon the future trends of using semantic factors to drive smartly coordinated active systems.", optnote="ISE", optnote="exported from refbase (http://refbase.cvc.uab.es/show.php?record=1814), last updated on Thu, 06 Mar 2014 12:41:15 +0100", isbn="978-0-85729-996-3", doi="10.1007/978-0-85729-997-0_2" }
