A statistical-mechanical view on source coding: physical compression and data compression
statistical-mechanical physical compression data compression
2010/11/23
We draw a certain analogy between the classical information–theoretic problem of lossy data compression (source coding) of memoryless information sources and the statistical mechanical behavior of a c...
Overlay Protection Against Link Failures Using Network Coding
Overlay Protection Link Failures Network Coding
2010/11/22
This paper introduces a network coding-based protection scheme against single and multiple link failures. The proposed strategy ensures that in a connection, each node receives two copies of the same ...

Relay Selection Network Coding Two-Way Relay Channels
2010/12/13
Abstract—In this paper, we consider the design of joint network coding (NC) and relay selection (RS) in two-way relay channels.In the proposed schemes, two users first sequentially broadcast their res...
Morphological dilation image coding with context weights prediction
quad-tree coding morphological dilation variable-length group test coding weights training
2010/12/14
This paper proposes an adaptive morphological dilation image coding with context weights prediction. The new dilation method is not to use fixed models, but to decide whether a coefficient needs to be...
