A lot of different algorithms for background prediction and memory control have been investigated mainly in the field of low bit-rate coding. Two problems arise with background prediction: 1. How to tell the receiver which parts of the prediction image may be taken from the background memory? 2. How to distinguish at the receiver’s side between object, stationary, covered and uncovered background? This paper presents a method for pel-accurate distinction between moving object and background without transmitting a single bit. In addition an object-oriented motion estimation and compensation is introduced.
