Abstract
A computer-implemented method and apparatus for encoding pictures of a sequence of pictures. According to a preferred embodiment, an encoding system determines a relatively fixed background of the sequence of pictures, and transmits the background to a decoding system. Foreground objects of a current picture are separated from the background, and motion compensation encoding of the foreground objects is performed with respect to at least one previous picture. The encoded foreground objects are then transmitted to the decoding system.
