This paper proposed a hybrid watermarking method that used dither quantization of Singular Value Decomposition (SVD) on average coefficients of Integer Haar Wavelet Transform (IHWT). The wa-termark image embeds through dither quantization process on singular coefficients value. This sche-me aims to obtain the higher robustness level than previous method which performs dither quanti-zation of SVD directly on image pixels value. The experiment results show that the proposed method has proper watermarked images quality above 38dB. ...
