Claim Text:
1. A video surveillance system comprising: two or more video cameras each providing a video signal, the cameras each being positioned at a respective known location; and circuitry configured to: detect image motion of an image feature within a first field of view of a first video camera of the two or more video cameras for deriving a corresponding physical motion of an object represented by the image feature; store data relating to a plurality of images of a plurality of the video signals from the two or more video cameras; derive the physical motion of the object with respect to a plurality of the known locations of the two or more video cameras; for forward prediction, derive a first expected time when the object may be observed in a second field of view of a second video camera of the two or more video cameras based on the derived physical motion and routing data defining possible routes from an observed location of the object in the first field of view to field of views of the two or more video cameras other than the first video camera; and display the images of the video signals from the second video camera stored in the circuitry at the first expected time, wherein for backward prediction, with respect to an image feature in an image under consideration, the circuitry is configured to derive the physical motion of the object prior to the object being observed in the image under consideration with respect to the plurality of the known locations of the two or more video cameras based on the plurality of images of the plurality of the video signals from the two or more video cameras stored in the circuitry, derive a second expected time before the time of the image under consideration when the object may have been observed in the second field of view of the second video camera, and access the plurality of images of the plurality of the video signals from the two or more video cameras stored in the circuitry within a threshold time of the derived second expected time.
