A Reliable SVD-DWT Based Watermarking Scheme with Artificial Bee Colony Algorithm
نویسندگان
چکیده
A robust image watermarking scheme based on singular value decomposition (SVD) and discrete wavelet transform (DWT) with Artificial Bee Colony Algorithm is proposed in this paper. Previous SVD based watermarking algorithms have a major drawback of false positive detection. For solving this problem, the similarity measure of U matrix for ownership is checked. To achieve the highest possible robustness without losing the transparency, an adaptive scale factor is obtained by the artificial bee colony (ABC) algorithm. Experimental results demonstrate that the performance of the proposed approach outperforms the existing methods.

In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive to it. To increase the robustness especially towards affine attacks, RDWT is adopted for its...
