Abstract :
This paper presents a simple Contourlet-based watermarking technique and investigates the role of Contourlet Transform (CLT) versus wavelet transform (WT) in achieving a high level of robustness. The same embedding strategy is adopted for both cases of CLT-based watermarking and WT-based watermarking. Experimental results show the superiority of the CLT-based watermarking technique over the WT-based one in resisting the investigated common signal processing attacks.
