An adaptive virtual re-partitioning-based windowing technique for motion compensation
J. Zhang, M. Omair Ahmad, M. N. S. Swamy · 2002
The authors describe a new windowing technique for frames partitioned region-wise or using variable-size blocks, where the virtual repartitioning operation for a given region is carried out adaptively and performed locally. Compared to the existing methods, this technique utilizes more pixels that are in the close neighborhood of the boundaries of the regions in the windowing operation, resulting in a substantial reduction in the prediction error as well as in the blocking effect.
