Abstract

In this paper, an improved blind color image watermarking algorithm based on relationship embedding strategy is proposed. Firstly, the original RGB color image is transformed into YCbCr color space. Secondly, the Y channel of YCbCr color space is divided blocks sized 8ž8, and then perform two dimensional discrete cosine transform on each block. Finally, embed binary watermarking signal by changing one pair selected middle-frequency sub-band coefficient's relationship. Experimental results show that the proposed algorithm has very good transparency and robustness against the common image processing. Compared with other similar algorithms, it has better performance
