Abstract

Certain configurations herein include changing the resolution of an auxiliary map (e.g. a motion map a z map etc.) at a first level of quality to obtain an auxiliary map at a second level of quality. For example changing the resolution can include receiving a respective auxiliary map of one or more vectors at one or more lower levels of quality and progressively refining via novel operations the auxiliary map to higher or lower levels of quality in a hierarchy.
