BER formulation for the blind retrieval of MPEG video watermark
TL;DR: A multiple watermarks embedding scheme based on multi-stage vector quantisation (VQ) has superior features than traditional VQ-based watermarking schemes not only in security, encoding time, and codebook storage space, but also in secret sharing ability.

Improvement of watermark detection process based on Bayesian estimation
TL;DR: The watermark detection problem is formulated as a kind of blind deconvolution problem, and a watermarks detection method using Bayesian estimation is proposed usingBayesian estimation.

Robust digital image watermarking scheme using wave atoms with multiple description coding
TL;DR: The experimental results indicate that superiority of the proposed method against common attacks such as JPEG compression, Gaussian noise addition, median filtering, salt and pepper noise, etc., compared with the existing watermarking schemes using multi-scale transformations.

Informed embedding for multibit watermarking
R.A. Silva,J. Mayer +1 more
TL;DR: The proposed system is analogous to code division multiplexing in spread spectrum communications and good system performance considering watermark properties of fidelity, efficiency, data payload and robustness against volumetric distortion sources is confirmed.
Geometric Distortion in Image and Video Watermarking. Robustness and Perceptual Quality Impact
TL;DR: This thesis discusses the two aspects of the geometric distortion problem, namely the watermark desynchronization aspect and the perceptual quality assessment aspect, and proposes a novel approach to quantify the perceptualquality impact of geometric distortion.

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.
Journal ArticleDOI
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.
