| Abstract: |
Motion information scalability is important for scalable bit-stream adaptation on low bit-rates, when motion rate occupies a significant portion of the total bit-rate. This type of scalability can be achieved by layered representation of motion block partitioning and predictive coding of associated motion vectors across these layers. So far, several approaches for creating layered motion structure targeting quality scalability have been proposed and in this paper their accuracy is evaluated. For that purpose optimal motion models have been found. It has been shown that simple evaluation of reconstruction error at the encoder side improves suboptimal modeling techniques. |
