Abstract: The present disclosure provides techniques for implementing a hierarchical and partitional integer motion estimation search (IMES) architecture using a search engine that is configurable based on a content of a plurality of frames in a video sequence. For example, the techniques include identifying, based on the plurality of frames, one or more search parameters for the hierarchical and partitional motion estimation, where the one or more search parameters are based on a content indicative of motion features tracked across the video sequence. The hierarchical and partitional motion estimation, which includes at least one decimated motion estimation search followed by a full-pixel level search, is performed based on the one or more identified search parameters to determine an integer (or pixel-level) motion vector.
