This paper describes a watermarking method to directly embed information into a CABAC entropy coded H.264/AVC stream. In theory, modification of a part of an arithmetically coded ...
Conventional digital video playback systems provide only limited user interactivity, mostly in the form of VCRlike controls such as fast forward/backward, slow motion, pause/stop,...
We present a streaming compression algorithm for huge time-varying aerial imagery. New airborne optical sensors are capable of collecting billion-pixel images at multiple frames p...
