Abstract :
A robust digital image watermarking scheme based on singular value decomposition (SVD) and discrete wavelet transform (DWT) is proposed in this paper. The algorithm is based on modifying the singular values of small blocks of the low-frequency approximation subband (LL) of the DWT domain to embed watermark into host image. Experimental results demonstrate the robustness against several common image-processing operations.
