    segmenting objects from the foreground image;

    tracking objects within the frame by identifying the largest connected components inside each objects region of interest;

    globally tracking positions of objects over time across multiple frames;

    fusing track data of objects obtained from multiple cameras to infer object positions; and

    resolving conflicts to estimate most likely object positions over time.
