Claim:
1. A computer-implemented method for focusing cameras on an area of activity in an event comprising: selecting salient objects from a field of view in a video stream, generated by a plurality of cameras, where saliency is determined by shape, appearance and motion of the objects; analyzing activity in the field of view to extract patterns from the field of view, where the patterns are at least one of temporal and spatial; determining a region of interest based on the extracted patterns and the selected salient objects in view of content specific rules corresponding to a type of the event, and based on a region in the field of view that is determined from the extracted patterns to have a relatively high degree of motion; and focusing one or more of the plurality of cameras on the determined region of interest based on the content specific rules, wherein the content specific rules comprise at least one rule for focusing the plurality of cameras on a portion of the region of interest based on the relationship of salient objects in the region of interest.
