Abstract

In general techniques are described for performing adaptive overlapped block motion compensation when coding video data. A video coding device configured to code video data may implement the techniques. The video coding device may comprise one or more processors configured to determine an adaptation metric from a region of support for one of a first partition and a second partition of one or more blocks of the video data separated by a partition boundary. The region of support may not be the entire one or more blocks of video data. The one or more processors may further be configured to adapt based on the adaptation metric application of an overlapped block motion compensation process to determine predicted pixel values near the partition boundary for a first predicted block representative of the first partition of the video block.
