Coder-oriented matching criteria for motion estimation [PDF]

open access: yes, 1996
Classical matching criteria for motion estimation determine the match quality by operating in the spatial domain. The resulting displaced frame difference signal is, however, compressed by means of frequency transformations, and any optimal matching ...

Composition of Motion Description Languages [PDF]

open access: yes, 2008
We introduce a new formalism to compose interacting heterogeneous systems described by extended motion description languages ( mdl es). The novelty lies in producing a composed system whose behavior could be a superset of the union of the behaviors of its generators. In the class of systems modeled using mdl es, the composition operator is closed, and
