Video watermark detection in DCT domain for H.264/AVC through a hierarchical prior
Antonis Mairgiotis,D.E. Ventzas +1 more
TL;DR: This work proposes a two-level hierarchical prior in the framework of intra-coded DCT (Discrete Cosine Transform) coefficients in H.264/AVC video stream, and shows improved detection performance along with improved robustness against different attacks.

Embedding biometric watermark on document image using discrete wavelet transform
Ioi-Tun Lam,Chi-Man Pun +1 more
TL;DR: Experimental results show that the proposed method is quite robust to various attacks such as Gaussian White Noise, JPEG Compression and Low-Pass Filters, and is successfully tested for embedding the fingerprint watermark message and extraction even if the watermarked document image has been attacked by some imitated interferences.

Digital watermarking: An approach based on Hilbert transform
TL;DR: In this paper, the authors proposed an algorithm for embedding and extracting watermark in a host image and analytically obtain a parameter related to this procedure, using extensive simulations, they show that the algorithm performs well even if the host image is corrupted by various attacks.

Hardware implementation of visible watermarking
TL;DR: The ultimate objective of the research is to develop low power, high performance, real-time, reliable and secured watermarking system which can provide robustness over certain attacks namely cover-up attack, cropping noise, scaling and geometric attacks.

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.
