TLDR
A copyright protection method that is based on hiding an ‘invisible’ signal, known as digital watermark, in the image is presented and a variation that generates image dependent watermarks as well as a method to handle geometrical distortions are presented.About:

Combinational image watermarking in the spatial and frequency domains
Frank Y. Shih,Scott Y.T. Wu +1 more
TL;DR: In order to provide more watermarks and to minimize the distortion of the watermarked image, a novel technique using the combinational spatial and frequency domains is presented in this paper.

Statistical analysis of watermarking schemes for copyright protection of images
TL;DR: In this article, a statistical approach to obtain models that can serve as a basis for the application of decision theory to the design of efficient detector structures was proposed, where the authors focus on the problem of the performance analysis of image watermarking systems that do not require the availability of the original image during ownership verification.

A novel DCT domain CRT-based watermarking scheme for image authentication surviving JPEG compression
TL;DR: A novel Chinese Remainder Theorem (CRT)-based technique for digital watermarking in the Discrete Cosine Transform (DCT) domain that is robust to several common attacks is proposed and compared with recently proposed Singular Value Decomposition (SVD)-based and spatial CRT-based watermarked schemes.

Invisibility and application functionalities in perceptual watermarking an overview
TL;DR: This paper provides a functional inventory of image watermarking applications and emphasizes the dependency between the application purpose and its need for invisibility, and presents a global framework common to most existing water marking systems.
Journal ArticleDOI
A robust image watermarking technique using SVD and differential evolution in DCT domain
TL;DR: In this paper, the authors applied differential evolution (DE) algorithm to balance the tradeoff between robustness and imperceptibility by exploring multiple scaling factors in image watermarking.

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.

The JPEG still picture compression standard
TL;DR: The Baseline method has been by far the most widely implemented JPEG method to date, and is sufficient in its own right for a large number of applications.

The JPEG still picture compression standard
TL;DR: The author provides an overview of the JPEG standard, and focuses in detail on the Baseline method, which has been by far the most widely implemented JPEG method to date, and is sufficient in its own right for a large number of applications.
