Abstract

The problem of wide-area surveillance from a set of cameras without reliance on calibration has been approached by many through the computation of “connectivity/visibility graphs.” However, even after constructing these graphs, it is not possible to recognize features such as holes in the coverage. The difficulty is not due to the techniques used for finding connectivity between camera views, but rather due to the lack of information in ...
