Watermarking with the UPC and DWT
Evelyn Brannock,Michael Weeks +1 more
TL;DR: Advancements in digital technologies offer new and easier methods in which consumers can purchase and enjoy creative content, for example, by downloading and viewing movies on a notebook computer, allowing those who wish to profit from digital media that they did not author and do not own to illegally profit from the efforts of others.

A new robust watermarking algorithm based on intra-frame difference
TL;DR: Based on spatial domain intra-frame difference, a new robust video watermarking algorithm is proposed in this paper , where frame sequences of the to-be-marked digital video are grouped based on the time period.
Adaptive video watermarking with robust pca-based decoding
TL;DR: The results show that the proposed method offers improved performance compared with several conventional methods and is much suitable for various security multimedia based applications.

Zero-Watermarking Algorithm for Remote Sensing Image via BEMD and DFT
TL;DR: In this paper , a remote sensing image zero watermarking algorithm based on bi-dimensional empirical mode decomposition (BEMD) and discrete Fourier transform (DFT) is proposed.

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.
