....marks in digital images have been inspired by methods of image coding and compression. Information has been embedded using the Discrete Cosine Transform (DCT) 6, 2] Discrete Fourier Transform (DFT) 7, 4] Wavelets [1] Linear Predictive Coding [5] Fractals [11] and Lapped Orthogonal Transforms [8] as well Current address: Siemens Corporate Research, 755 College Road East, Princeton, NJ, oruanaidh scr.siemens.com as in the spatial domain [10, 12] Recently work has also been done on watermarks which take into account the behavior of human visual system. Objective criteria for measuring ....
