Abstract	For encoding moving images at very low bit rates, object-oriented analysis-synthesis coding using source models of moving 2-D and 3-D objects has been investigated. According to this coding concept, each moving object of an image is described and encoded by three parameter sets defining the motion, the shape, and the surface color of the moving object. The parameters to be coded are dependent on the source model being applied. Thus, the coding efficiency of object-oriented analysis-synthesis coding can be evaluated by comparing the encoded parameter bit rates for a fixed picture quality. The results obtained with source models of moving 2-D and 3-D objects are compared with those of a standard H.261 coder at a bit rate of 64 kbit/s. The source models of flexible 2-D and rigid 3-D objects are more efficient than source models which are based on rigid 2-D objects or on moving blocks as in a H.261 coder.<>
