Abstract
A system and method for performing motion estimation. Interlaced frames are reduced in resolution using field based scaling, and a first search is performed on the reduced resolution frames. This first search is performed by computing motion errors between the fields of a current frame and the fields of a reference frame to obtain vectors that approximately describe inter-field motion. These same motion errors are used to compute frame errors, which are used to obtain vectors that approximately describe inter-frame motion. The approximate field and frame vectors are then refined to get more precise vectors.
