Quality Evaluation of Digital Image Watermarking

In the last few years, digital image watermarking have been proposed as a solution for solving the illegal copying and proof of ownership problem in the context of multimedia object. But it is still difficult have a rough standard of their performances and hence to compare them. So we propose a suggestion standard based on the hiding property and robustness of digital watermark, describe a series of evaluation methods and analyze the performances of the common evaluation tools. We also designed an evaluation process for image digital watermarking and give a basic necessary condition to judge the validity of image watermarking.
