Abstract
There exists a strong duality between Source Coding with side information (known as Distributed Source Coding) and Channel Coding with Side Information (informed data-hiding). Inspired by the system in [1], which is a combination of Data Hiding and Distributed Source Coding scheme, we have extended this system to 2D natural images. Hence a cascade of informed data hiding for a still image is followed by a distributed source coding with a fidelity criterion, given that a noisy version of the input image is available only at the decoder. We used baseline JPEG compression with different quality values for creation of the Side Information, a memoryless quantization for informed data hiding, and LDPC based coset construction for source coding. The preliminary experimental results are given using the theoretical findings of the duality problem.
