摘要:	The digital watermark is a powerful technique to identify copyright information. A watermark is an image embedded in the original image, and can be extracted correctly by the watermark extracting method to prove the copyright ownership. Furthermore, it is difficult for the human visual system to detect the differences between the original image and the one with a watermark. This paper proposes a renovated watermarking technique for the image in the spatial domain based on the pixel relationships. To examine the robustness of our method, we apply the JPEG losing compression process and several image processes, such as blurring, sharpening and noise adding…etc., to attack the watermark based on our method. The experimental results show that our approach is better than the others in its robustness of surviving different attacks.
