Abstract
Image sequences are mostly coded by motion compensated predictive coding. The motion vector field to be transmitted as side information is typically predictive coded. In this paper a new approach is presented for coding of motion vector fields at low bit rates (<64 kbit/s) more efficiently by applying a pyramid decomposition, which is encoded using zero-trees. The embedded coding of the pyramid allows for progressive transmission of the motion vectors and is well suited for source adaptive channel coding
