Abstract
An apparatus having a processor and a circuit is disclosed. The processor may be configured to (i) compare, at a first level of a motion estimation hierarchy, first units of a current picture with a reference picture to generate first metrics, (ii) combine, at the first level, the first metrics to generate second metrics and (iii) refine, at a second level of the hierarchy, the first metrics and the second metrics to generate motion vectors. Multiple metrics may be refined in parallel. The first metrics generally correspond to the first units in an overlapping unit of the current picture. The second metrics generally correspond to a plurality of second units in the overlapping unit. Each second unit may overlap one or more first units. The circuit may be configured to process the overlapping unit based on the motion vectors to generate an output signal.
