Overview: This paper proposes an advanced motion threading technique to improve the existing Motion Threading Technique for wavelet video coding. With a lifting-based temporal wavelet structure, the boundary effect problem caused by artificial thread truncation in the original MT is well solved. Fractional-pixel motion can also be applied in the new structure. Multi-layer motion threading is used to achieve efficient frame-rate scalability. To efficiently reduce the motion cost as well as achieve good frame rate scalability, it analyzes both the interlayer and the intra-layer correlations. A novel R-D optimized Correlated Motion Estimation (CME) scheme is proposed for the motion estimation process.
