Abstract: A DWT-HMM image watermarking algorithm with content-adaptive approach is proposed in this paper to optimized the trade-off between robustness and visual quality, which is characterized as follows: 1) The entropy mask proposed by Watson is constructed in wavelet domain; 2) The LHVS and entropy masks are used as the measures to adaptively select image components for watermarking; 3) RA code with erasure and error correction is employed to synchronize the watermarked image; 4) A posterior HMM is utilized in watermarking. Considerable improvement in robustness performance with the proposed adaptive algorithm is obtained over the previous DWT-HMM watermarking algorithm with stochastic embedding.
