Aiming at problem of Ghost regions and flicker pixels interference which are existed in target extracted by traditional Vibe moving objects detection algorithm

an improved Vi Be algorithm is proposed based on surendra background update algorithm. Characteristics of quick update background of surendra algorithm are applied to iterate and get pure background. Detect foreground of Vi Be algorithm are pixel labeled and ghost identified to remove ghost and flicker pixels point. New foreground is output. Experimental results show that the proposed algorithm can effectively remove ghost of foreground detection of Vi Be algorithm

and can restrain the flicker pixels noise

and get more accurate foreground image.
