Image-adaptive SVD watermarking algorithm based on wavelet perceptual model
|
Abstract:
A SVD blind watermarking algorithm was proposed using a wavelet perceptual model, which was adaptive to the host image features. In order to maximize the intensity of watermark embedding, the quantization steps associated with different image features were determined by the significant wavelet coefficients, and a good tradeoff between the transparency and the robustness of the algorithm was achieved. Experiments show that the proposed algorithm is effective and robust to common image processing operations.
