Abstract :
In this paper we propose a new method for content reconstruction using self-embedding technology. As the content reconstruction problem can be regarded as a special kind of erasure channel, we use fountain code which has good performance in erasure channel to generate reference symbols for reconstruction. Theoretical analysis of success bound about maximal tamper rate is given and is verified by the Monte Carlo simulation. The experiments of a specific scheme show that our method can reduce the payload and improve the quality of the watermarked image, while still achieving high quality reconstruction and high tamper tolerance.
