Abstract—In this paper, we present a new, robust digital watermarking scheme for ownership protection. The scheme is based on Steerable Pyramid (SP) and discrete cosine transform (DCT) using Pearson product moment correlation. During the process of watermark embedding, SP is performed on original host image, and corresponding oriented sub-band is selected to carry the watermark. DCT is applied to each block of size 8x8 of the selected sub-band. Two independent streams representing the watermark are embedded in low and mid-frequency of DCT components. Watermark detection is based on comparison result between Pearson product moment correlations of the two independent streams with each watermarked block. The experimental results demonstrate good visual imperceptibility and resiliency of the proposed scheme against an intentional and un-intentional variety of attacks.
Index Terms—Robust image watermarking, Steerable pyramid, Pearson product moment correlation, discrete cosine transform, Geometric attacks.
