Hierarchical block-motion estimation using linear model-based postprocessing
Kang-Soo Seo, H.-K. Kim · Electronics Letters · 1993
A two-hierarchy block-motion estimation method is proposed which uses a postprocessor based on a linear model of the blockmotion vector field. Postprocessing in each hierarchy uses the linear model to correct false motion vectors estimated by blockmatching. By depending on a weighting parameter and window size for the correction, the global or local motion is effectively generated at each hierarchy.
