This paper presents a novel blind robust digital image watermarking scheme using nonnegative matrix factorization (NMF) in DWT domain. Firstly, the original image is transformed into some subband coefficients using discrete wavelet transformation (DWT), and then a Gaussian pseudo-random watermark se
