Foreground segmentation mask
WebFor every frame in each sequence, a binary foreground mask of the object is computed using background segmentation techniques. Instead of explicitly storing the complete silhouette , we compute and store only the convex hull and its dual representation, as shown in Figure 2.3 for every video frame.
