Spread Spectrum Watermark Embedder Optimization Using Genetic Algorithms
TL;DR: Simulation results show that optimizing the number of cover signal points, payload capacity and watermark signal-to-interference ratio, better acceptable values of both BER and PAD can be achieved simultaneously.

Improving the security of watermark public detectors
Mohamed F. Mansour,A.H. Tewfik +1 more
TL;DR: A generalized attack for removing the watermark with minor perceptual distortion and establish its effectiveness using a direct implementation with least mean square (LMS) algorithm and a counterattack by using fractal decision boundaries, which are obtained by processing the original boundary.

A maximum a posteriori identification criterion for wavelet domain watermarking
N.T. Ming,Hari Krishna Garg +1 more
TL;DR: An MAP detector in the discrete wavelet transform domain is proposed, based on modeling the wavelet coefficients by a generalized Gaussian distribution, and shown to be optimum and robust to common image processing operations.

Optimal multiuser spread-spectrum data hiding in digital images
TL;DR: This work gives an orthogonal set of embedding spread-spectrum signatures that achieves maximum sum signal-to-interference-plus-noise ratio at the output of the linear-filter receivers for any fixed embedding amplitude values.

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.
