In this paper, we propose a rewritable data embedding scheme on MPEG coded data domain for content managements including DRM, content controlling and indexing. Data embedding is p...
The consideration of better motion compensation techniques for inter-frame prediction is one of the key reasons why the new H.264 (MPEG-4 AVC) video coding standard can achieve co...
In this paper, we propose a distributed 3D dynamic mesh coding system. The system is based on Slepian and Wolf’s and Wyner and Ziv’s information-theoretic results. Our system ...
The current solutions to disclosing privacy in computer-mediated communication are two-fold: either the connection is permitted and an audio-video link is opened providing a full-b...
Matching pursuit (MP) based video coder represents an effective alternative to conventional block based DCT based architectures[I]. In this paper we propose a generalized motion c...
