Abstract

Reference frames are generated by applying spatial filtering to decoded video frames after pixel reconstruction. For encoding video signals, the reference frames are used to encode subsequent video frames using interframe encoding. For decoding video signals, the reference frames are used to decode subsequent video frames using interframe decoding. In a preferred embodiment, motion estimation and motion compensation form part of the interframe encoding and decoding procedures.
