Abstract：

Background images play an important role in the rapid extraction of foreground objects from their background scene. In this paper, a new technique of background image generation via the use of partial background images is presented. Partial background images are helpful in facilitating the progressive process of image extraction and may also eliminate the unstable effects of the camera's physical vibrations. In this method, histograms are utilized to record and trace the changes in intensity in order to determine the best background values. This procedure does not require a large space in which to store the image sequences, and it is fast since the constructing and updating processes can be performed simultaneously. Moreover, variations in illumination or in the weather may be tolerated during background image generation, and the method is applicable to both gray and color images. The feasibility of the proposed technique is strongly suggested by our experimental results, which are reported at the end of this paper.
