Abstract

According to the analysis and research of theories of discrete cosine transform (DCT) and discrete wavelet transform (DWT), this paper puts forward an improved algorithm realizing digital image watermark embedding in the transform domain. On the basis of deeply understanding that the coefficient of a digital image after wavelet transform has correlation, it carries out DCT transform of the transformed digital image coefficient and then embeds digital watermarks, which makes the algorithm have the characteristics of the two transforms and strengthens the robustness of watermarking algorithm.
