Block-based motion estimation for missing video frame interpolation, and spatially scalable (multi-resolution) video coding

Video frames are often dropped during compression at very low bit rates. At the decoder, a missing frame interpolation method synthesizes the missed frames. We propose a two step motion estimation method for the interoplation. More specifically, the coarse motion vector field is refined at the decoder using mesh-based motion estimation instead of using computationally intensive dense motion estimation.
