Joint Data Hiding and Wyner-Ziv Coding, Theory and Practice

چکیده
This paper considers the joint problem of dirty-paper and Wyner-Ziv coding with partial host information at the receiver. The rate-distortion and the capacity expressions have been derived for the Gaussian case. It is shown that the availability of the partial host information to the receiver has positive effects to the compression performance and the overall capacity. Moreover, a practical coding scheme is proposed which is based on Trellis Coded Quantization (TCQ) codes, and Low Density Parity Check (LDPC) codes. Simulation results show that the Wyner-Ziv and watermarking schemes approach the derived rate-distortion and capacity bounds respectively.

Successive Wyner-Ziv Coding Scheme and its Application to the Quadratic Gaussian CEO Problem
We introduce a distributed source coding scheme called successive Wyner-Ziv coding scheme. We show that any point in the rate region of the quadratic Gaussian CEO problem can be achieved via the successive Wyner-Ziv coding. The notion of successive refinement in the single source coding is generalized to the distributed source coding scenario, which we refer to as distributed successive refinem...

The combination of source coding with decoder side-information (Wyner-Ziv problem) and channel coding with encoder side-information (Gel’fand-Pinsker problem) can be optimally solved using the separation principle. In this work we show an alternative scheme for the quadratic-Gaussian case, which merges source and channel coding. This scheme achieves the optimal performance by a applying modulo-...
متن کاملJoint Decoding and Correlation Channel Parameter Estimation in Wyner-Ziv Video Coding
In Wyner-Ziv (WZ) video coding, or coding of video with decoder side information (SI), the correlation between the source and its SI at the decoder side is modeled as a virtual correlation channel, and decoding of the quantized source requires the estimation of the correlation channel parameter. In this paper, we present a joint decoding and correlation channel parameter estimation approach. In...
متن کاملWyner-Ziv Video Coding using Hadamard Transform and Deep Learning
Predictive schemes are current standards of video coding. Unfortunately they do not apply well for lightweight devices such as mobile phones. The high encoding complexity is the bottleneck of the Quality of Experience (QoE) of a video conversation between mobile phones. A considerable amount of research has been conducted towards tackling that bottleneck. Most of the schemes use the so-called W...
