Optimum detection of multiplicative watermarks using locally optimum decision rule
Qiang Cheng,Thomas S. Huang +1 more
TL;DR: New detector structures for the optimum detection of multiplicative watermarks are derived and it is shown that the observations should be raised to the power of the shape parameter of the distribution before they are correlated with the watermark.

MPEG-2 digital video watermarking technique
TL;DR: A new compressed domain video watermarking scheme is presented that embeds several binary images decomposed from a single watermarked image into different scenes in a video sequence and incorporates a visual mask based on local image characteristics into the compressed bit streams.

A Novel Robust Colour Watermarking Scheme for Colour Watermark Images in Frequency Domain
TL;DR: A novel and robust colour water marking scheme of embedding colour watermark into colour host image that is more secure, robust and efficient because of use of DWT and DCT.
Proceedings ArticleDOI
Audio watermarking using wavelets
TL;DR: An imperceptible and robust audio watermarking algorithm based on the discrete wavelet transform (DWT) is described that has been evaluated extensively, and simulation results demonstrate the imperceptibility (inaudibility) and robustness of the proposed algorithm.

A Robust Digital Watermarking of Satellite Image at Third Level DWT Decomposition
TL;DR: The experimental results demonstrate the efficiency of the proposed scheme, which fulfills the strict requirements concerning alterations of satellite images, and provides a third level DWT decomposition of the satellite image by choosing a region of interest and embedding the watermark in the same.

Secure spread spectrum watermarking for multimedia
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.

Techniques for data hiding
TL;DR: This work explores both traditional and novel techniques for addressing the data-hiding process and evaluates these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.

A digital watermark
TL;DR: The paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512/spl times/512 intensity image with an 8 bit gray scale, capable of carrying such information as authentication or authorisation codes, or a legend essential for image interpretation.

Image coding based on a fractal theory of iterated contractive image transformations
TL;DR: The author proposes an independent and novel approach to image coding, based on a fractal theory of iterated transformations, that relies on the assumption that image redundancy can be efficiently exploited through self-transformability on a block-wise basis and approximates an original image by a Fractal image.
