133 A Wavelet Transform Based Self-Adaptive Watermarking Algorithm for Color Image Available to Purchase

It is known that the robustness of watermark is relevant to position and the embedding intension of the watermark. This paper introduces the color image watermarking algorithm based on robust wavelet transformation, and provides a wavelet JND model of the property of human visual system, and does research on color image digital watermarking algorithm base on HVS, including algorithm model, program flowchart and the experiment result to maintain the visual perception effect of the original image and improve the watermark robustness.
