Abstract—Digital watermarking techniques have been developed to protect the copyright of multimedia objects such as text, audio, video, etc. In this paper, we propose a new digital watermarking algorithm with gray image based on discrete wavelet transform (DWT), 2 dimensions discrete cosine transform (DCT) and singular value decomposition (SVD) for robust watermarking of digital images in order to protect digital media copyright efficiently. One of the major advantages of the proposed scheme is the robustness of the technique on wide set of attacks. Experimental results confirm that the proposed scheme provides good image quality of watermarked images. Index Terms—Digital image watermarking, DWT, DCT PSNR, SVD.
