Singular value decomposition (SVD) is a valuable transform technique used in watermarking applications. Instead of using singular values (SV) to embed the watermark as in other SVD based methods, the reference of the original image is obtained from truncated SVD by using some of the singular values, and the watermarking is done according to difference of the original and its reference image. The method is compared with discrete wavelet transform (DWT) based approach and its performance against some attacks is discussed.
