    The history of noise [on the 100th anniversary of its birth]
    Cohen, L.
    Signal Processing Magazine, IEEE
    Volume 22, Issue 6, Nov. 2005 Page(s): 20 - 45
    Digital Object Identifier 10.1109/MSP.2005.1550188
    Summary: In this paper, the author conveys some of the vibrant history of noise that has been involved in the solution of some of the greatest scientific, mathematical, and technological problems. This paper aims to show that the history of noise is an exciting story filled with drama and worth telling.

    Khi ngã ta lại hỏi
    Ngã lần này có đứng dậy nữa không

                  Summary:We present a variant to the DCT-based block algorithm proposed in Hsu and Wu (1996) for signal embedding in digital images. Instead of inter-block relations, our algorithm uses intra-block relations to generate the watermarked image. We describe the algorithm and its performance against translation and cropping. The features of our method are: (1) the watermark is perceptually invisible; (2) little loss of relevant information of original image; (3) the watermark can be retrieved by using a secret key; and (4) the watermark is robust against translation and area cropping

                            Novel DCT and DWT based Watermarking Techniques for Digital Images

                            Novel DCT and DWT based Watermarking Techniques for Digital Images
                            Tripathi, S.; Jain, R.C.; Gayatri, V.
                            Pattern Recognition, 2006. ICPR 2006. 18th International Conference on
                            Volume 4, Issue , 0-0 0 Page(s):358 - 361
                            Digital Object Identifier 10.1109/ICPR.2006.872
                            Summary:Two digital image watermarking techniques that have higher level of security compared to most of the existing algorithms have been proposed. The proposed digital watermarking scheme uses the properties of discrete cosine transform (DCT) and discrete wavelet transforms (DWT) to achieve almost zero visible distortion in the watermarked images. These techniques use a unique method for spreading, embedding and extracting the watermark. Embedding using a linear relation between the transform coefficients of the watermark and a security matrix has been proposed with satisfactory results. It has been shown that instead of adding the watermark to the source image, as is normally done, multiplying the watermark with the transformed source could be a preferred technique, as it would retain the original bit rate to a large extent. The watermarked images were tested subject to image cropping
