Optimal Prefix Codes for Some Families of Two-Dimensional Geometric Distributions
Lossless compression is studied for pairs of independent integer-valued symbols emitted by a source with a geometric probability distribution of parameter q (0, 1). Optimal prefix...

Arbitrary source models and Bayesian codebooks in rate-distortion theory
-- We characterize the best achievable performance of lossy compression algorithms operating on arbitrary random sources, and with respect to general distortion measures. Direct an...

Functional compression through graph coloring
Motivated by applications to sensor networks and privacy preserving databases, we consider the problem of functional compression. The objective is to separately compress possibly c...

Universal Coding on Infinite Alphabets: Exponentially Decreasing Envelopes
This paper deals with the problem of universal lossless coding on a countable infinite alphabet. It focuses on some classes of sources defined by an envelope condition on the margi...

Wyner-Ziv Video Coding Based on Turbo Codes Exploiting Perfect Knowledge of Parity Bits
In a Wyner-Ziv video coding system based on turbo codes, parity bits are generated for a Wyner-Ziv frame and transmitted to the decoder. In this context of distributed source codi...
