Abstract
Systems and methods are presented for processing sequences of video frames in a distributed video coding environment. Video frames chosen as key video frames are encoded in their entirety on a sending device, and the encodings are forwarded to a receiving device. Non-key video frames are partitioned into blocks of pixels which are individually processed at the sending device. Some pixel blocks are designated for reconstruction at the receiving device using a similar corresponding pixel block from a previous video frame, and the sending device does not encode those pixel blocks. Other pixel blocks are compressed at the sending device into representations that are sent to the receiving device to facilitate reconstruction of the other pixel blocks at the receiving device. Exceptional efficiency and accuracy may be achieved by employing spatiograms and singular value decompositions in processing pixel blocks of the non-key video frames at the sending device.
