Abstract

In this paper, we propose a new robust digital image watermarking scheme which integrates the Discrete Cosine Transform (DCT) and the Fast and Adaptive Bidimensional Empirical Mode Decomposition (FABEMD). The use of the FABEMD decomposition is motivated by the fact that FABEMD has better quality than any other decomposition technique in extracting intrinsic components known as Bidimensional Intrinsic Mode Functions (BIMFs) and residue. In the proposed approach, the watermark is embedded in the DCT coefficients of the residue, in order to achieve better performance in terms of perceptually invisibility and the robustness of the watermark. Experimental results and comparison analysis demonstrate that our method has better performance than the traditional watermarking method operating in the DCT domain.
