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

The late William Feller used to say: "I could'stare all my life at a symmetric matrix, I will never get Hilbert space out of it!" And sure enough, Hilbert space has proved to be one of the richest inventions of the mathematical mind. Like a good invention, just at the point when everyone thinks her
