Abstract

A method for improving the watermark extraction performance of the digital watermarking based on the modification of image pixels is proposed in this paper. By embedding the watermark in the chrominance channel and using the Weiner filter with 3x3 window size in the watermark extraction process, the accuracy of the extracted watermark can be improved. Sets of experiment are carried out to prove our proposed concept. The results obtained show that the improved performance in term of NC, compared to the previous method in [7], is achieved by using our proposed watermarking method. The improved robustness of the proposed method against various common imaging processing based attacks is also presented and discussed. ฉ2009 IEEE.
