Abstract
A cooperative camera network involving segmenting an image of an object and extracting a color signature from it. The color signature may be matched with the other signatures in an attempt to identify the object. There also can be combining and fusing the tracking of people and objects with image processing and the identification of the people and objects being tracked in an area or facility.

15. A method for identifying an object comprising:
-
obtaining a first image-of a scene;
obtaining a second image of the scene;
differencing the first and second images into a segmented image having substantially dissimilar regions of the first and second images removed;
thresholding regions that have a set threshold level of dissimilarity and adding them to the segmented image;
; and
extracting a color signature from the segmented image; and
matching the color signature with a color signature in a database. - View Dependent Claims (16)
