REUSE OF A SEARCH REGION IN MOTION ESTIMATION OF MULTIPLE TARGET FRAMES

摘要

Several methods and a system to reuse a search region in motion estimation of multiple target frames are disclosed. In an embodiment, a method includes acquiring a search region of a reference frame. The method also includes maintaining the search region in a memory. In addition, the method includes performing motion estimation of a macroblock of a target frame in a direction using a processor and the search region. The method also includes reusing the search region maintained in the memory to perform motion estimation of an additional macroblock of an additional target frame in an additional direction. The method may include reusing the search region maintained in the memory to perform motion estimation of a separate macroblock of a separate target frame in a separate direction.
