Value Decomposition

For invisibility and robustness are difficult to reconcile, a combination of singular value decomposition (SVD) and the discrete wavelet transform (DWT) of the color image adaptive watermarking algorithm is proposed. In the embedding process, modification of the singular value of LL band and LH band exploited to the watermarking scheme which excellent preserves the quality. The additional advantage of the proposed technique is taking advantage of HVS which can adaptively regulate the watermark embedding strength. Experimental results show that the algorithm not only has better transparency, but also has good robustness such as noise, compression, filtering, cropping.

Content Information

A new color image watermarking scheme is presented. The visual characteristics of HVS, multi-resolution of discrete wavelet transform, and color image content information are adopted to classify the wavelet coefficients and find a new JND model. The embedded watermark is processed by Arnold transform and chaotic modulation, which can improve the security of scheme. The combined JND model-guided watermarking scheme provides the maximum strength transparent watermark to compromise the robustness and invisibility. Both better invisibility and robustness work than other algorithms based on HVS are shown in the experimental results.
