Prefilter Control Scheme for Low bitrate TV Distribution
In IP-based TV distribution, coding degradation is sometimes evident in critical scenes because the bit rate for compression is rather low. Prefiltering is an effective counterme...

Distributed Estimation over Wireless Sensor Networks with Packet Losses
A distributed adaptive algorithm to estimate a time-varying signal, measured by a wireless sensor network, is designed and analyzed. The presence of measurement noises and of packe...

Overlapped Quasi-Arithmetic Codes for Distributed Video Coding
This paper describes Slepian-Wolf codes based on overlapped quasi-arithmetic codes, where overlapping allows lossy compression of the source below its entropy. In the context of s...

Distributed Estimation in a Power Constrained Sensor Network
— This paper derives the optimum non-uniform quantization scheme for a distributed estimation problem based on noisy observations in a wireless sensor network. The optimal quanti...

Parameter estimation for an H.264-based distributed video coder
In this paper we present a statistical model used to select coding parameters for a mixed resolution Wyner-Ziv framework implemented using the H.264/AVC standard. This paper exten...
