Reconstruction of frame backgrounds using camera parameters and a background panorama

In a video surveillance system, the background extraction of video frames plays an important role for the segmentation and recognition of surveillance objects, and even video compression. Since a video frame background can be obtained by tailoring a background panorama, a theoretical relation between the frame background and camera parameters along with a high resolution background panorama is established through the imaging geometry in this paper. An application instance shows that the deduced formula can reconstruct correctly video frame backgrounds, and on this basis, surveillance objects can be segmented easily.
