The duality between information embedding and source coding with side information and some applications
Aspects of the duality between the information-embedding problem and the Wyner–Ziv problem of source coding with side information at the decoder are developed and used to establish a spectrum new results on these and related problems, with implications for a number of important applications. The singleletter characterization of the information-embedding problem is developed and related to the c...
متن کاملSource Coding with Decoder Side Information
In this report, we study source coding problems with decoder side information (SI). Source coding problems with decoder side information are a special case of distributed source coding problems. We outline the relation between various distributed source coding problems in Table 1 with the help of Figure 1. For reference, we also include the standard single-source lossless and lossy compression ...
متن کاملDistributed single source coding with side information
In the paper we advocate image compression technique in the scope of distributed source coding framework. The novelty of the proposed approach is twofold: classical image compression is considered from the positions of source coding with side information and, contrarily to the existing scenarios, where side information is given explicitly, side information is created based on deterministic appr...
متن کاملSource Coding With Encoder Side Information
We introduce the idea of distortion side information, which does not directly depend on the source but instead affects the distortion measure. We show that such distortion side information is not only useful at the encoder, but that under certain conditions, knowing it at only the encoder is as good as knowing it at both encoder and decoder, and knowing it at only the decoder is useless. Thus d...
متن کاملSource Coding with Fixed Lag Side Information
We consider source coding with fixed lag side information at the decoder. We focus on the special case of perfect side information with unit lag corresponding to source coding with feedforward (the dual of channel coding with feedback) introduced by Pradhan [8]. We use this duality to develop a linear complexity algorithm which achieves the rate-distortion bound for any memoryless finite alphab...
