Combined DWT-DCT Digital Image Watermarking
TL;DR: An imperceptible and a robust combined DWT-DCT digital image watermarking algorithm that watermarks a given digital image using a combination of the Discrete Wavelet Transform (DWT) and thediscrete Cosine transform (DCT).

On the Gaussian watermarking game
Alejandro Cohen,Amos Lapidoth +1 more
TL;DR: It is shown that under the additive attack restriction, capacity turns out to coincide with the capacity of Costa's (1983) model for "writing on dirty paper," thus demonstrating that additive attacks are suboptimal.

Lossless watermarking for image authentication: a new framework and an implementation
TL;DR: A novel framework for lossless (invertible) authentication watermarking is presented, which enables zero-distortion reconstruction of the un-watermarked images upon verification and enables public(-key) authentication without granting access to the perfect original and allows for efficient tamper localization.

Attributing Fake Images to GANs: Learning and Analyzing GAN Fingerprints
TL;DR: The first study of learning GAN fingerprints towards image attribution and using them to classify an image as real or GAN-generated is presented, showing that GANs carry distinct model fingerprints and leave stable fingerprints in their generated images, which support image attribution.

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.
