“…There is an inherent trade-off between the accuracy of object segmentation and the overhead for coding the description of the segmentation. Segmentation can be very useful for videophone coding, where it is possible to exploit extensive a priori knowledge about the scene (e.g., existence of a face symmetry axis and relative approximate locations of the primary facial features) (see, e.g., [29]).…”
