Abstract

The Block Matching Algorithms used in most popular video codec standards introduce blocking artifacts which must be removed via residual coding or deblocking filters. Alternative transform stages that do not cause blocking artifacts, such as lapped transforms or wavelets, require motion compensation methods that do not produce blocking artifacts, since they are expensive to remove. We design a new Overlapped Block Motion Compensation (OBMC) scheme that avoids these artifacts while allowing adaptive blending window sizes. This has the potential to show significant visual quality improvements over traditional OBMC.
