8 pages, 12 figures.-- Contributed to: Second ACM/IEEE International Conference on Distributed Smart Cameras (ICDSC'2008, Stanford, California, US, Sep 7-11, 2008).One of the main characteristics of a visual sensor network environment is the high amount of data generated. In addition, the application of some process, as for example tracking objects, generate a highly noisy output which may potentially produce an inconsistent system output. By inconsistent output we mean highly differences between tracking information provided by the visual sensors. A visual sensor network, with overlapped field of views, could exploit the redundancy between the field of view of each visual sensor to avoid inconsistencies and obtain more accurate results. In...
