A new motion compensation method using superimposed inter-frame signals

A new MCP method called Neighbor Predicted Superimposed Search (NPSS) algorithm that uses superimposed inter-frame signals to achieve higher prediction accuracy is proposed in this paper. It outperforms other Multi-Hypothesis MCP (MHMCP) methods as it does not require the transmission of multiple motion vectors. The proposed method has better prediction quality and yet having comparable computational complexity as conventional block-based MCP with no extra side-information overhead.
