On Scalable Source Coding for Multiple Decoders with Side Information
The problem of side-information scalable (SIscalable) source coding and the problem of successive refinement in the Wyner-Ziv (SR-WZ) setting are considered in this paper. Both problems can be understood as special cases of the general problem of scalable lossy source coding for multiple decoders with access to side informations, but the encoder does not. In the former problem, the quality of t...
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...
