| Abstract(in English) | We propose a new method for digital watermarking with high quality image based on wavelet transform. We utilize wavelet transformed coefficients and the near space coefficients to find inconspicuous part of image. Therefore, we can accurately have embedded digital watermarking to near edges part in the inverse transformed image. According to the knowledge of human vision, edges are the most inconspicuous part of image. As a result of some experiments, we have confirmed these effects. |
