Abstract

Image background segmentation is one of the most prominent steps in many applications of the image processing. Several algorithms exist for the background segmentation from the dynamic scenes of a video sequence. However, elimination of background from the static images still remains a challenging task. Although trivial background subtraction algorithms can execute quickly, they do not give useful results in most situations. This paper addresses the issue of identifying and segmenting theft images captured from the background regions of the image to alert the user. Objective is to segment foreground object from the background region. An alert signal is produced to enable the user to initiate suitable action.
