| Abstract: | The communication system model of digital image watermarking was proposed by using its traditional one.Then the channel capacity of watermarking system was analyzed and validated from the view of information theory.A simple method was given to calculate the capacity of a digital image watermarking and the experimental results showed that the method was effective and feasible. |

| Keywords: | digital watermarking communication model of watermarking channel capacity watermarking capacity |
