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:

A robust digital image multi-watermarking scheme in the DWT domain
Yaxun Zhou,Wei Jin +1 more
TL;DR: The experimental results show that one of multi-watermarks is robust enough against the common image processing such as noise addition, filtering, and JPEG compression, while the other two watermarks are immune to any image attacks.

Generation and detection of watermarks derived from chaotic functions
Aidan Mooney,John G. Keating +1 more
TL;DR: The impact of the theoretical properties of the logistic function for several chaos-based watermark generation techniques, in particular, their highpass and lowpass properties, which when embedded in digital media, are suitable for correlation and statistical based detection methods.

A Hybrid robust watermarking system based on discrete cosine transform, discrete wavelet transform, and singular value decomposition
TL;DR: In this paper , a hybrid blind digital image watermarking with a combination of discrete cosine transform (DCT), DWT, and singular value decomposition (SVD) is proposed.

A robust and secure image watermarking scheme using SURF and improved Artificial Bee Colony algorithm in DWT domain
TL;DR: Experimental outcomes demonstrated that compared with the related existing schemes, this scheme exhibits an overall superior performance in the aspects of security, imperceptibility and robustness.

Object-based quality of service assessment using semi-fragile tracing watermarking in MPEG-4 video cellular services
TL;DR: An object-based system for quality of service assessment is presented to evaluate blindly the quality of a multimedia communication link by means of an unconventional use of semi-fragile digital 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.
