Research on the Wavelet-Based Adaptive Digital Watermarking Algorithm

In this paper, a wavelet analysis is based on digital image watermark embedding and extraction algorithms, according to the algorithm designed and implemented in the visual sense with intuitive binary image watermark in the gray image of the hidden and extraction, and carried out a simulation experiment. The experimental results show that the algorithm research paper is feasible, from the visual point of view embedded watermark image and there is no difference between the original image, extract the watermark is also clearly visible, and the algorithm is simple and easy to implement.
