Motion Estimation and Signaling Techniques for 2D+t Scalable Video Coding
EURASIP Journal on Advances in Signal Processing, 2006 We describe a fully scalable wavelet-based 2D+t (in-band) video coding architecture. We propose new coding tools specifically designed for this framework aimed at two goals: reduce the computational complexity at the encoder without sacrificing ...

A Framework for Adaptive Scalable Video Coding Using Wyner-Ziv Techniques
EURASIP Journal on Advances in Signal Processing, 2006 This paper proposes a practical video coding framework based on distributed source coding principles, with the goal to achieve efficient and low-complexity scalable coding. Starting from a standard predictive coder as base layer (such as MPEG-4 baseline

Automated techniques for provably safe mobile code
Theoretical Computer Science, 2003 We present a general framework for provably safe mobile code. It relies on a formal definition of a safety policy and explicit evidence for compliance with this policy which is attached to a binary. Concrete realizations of this framework are proof-carrying code, where the evidence for safety is a formal proof generated by a certifying compiler, and ...
