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:

Robust and adaptive watermarking technique for digital images
TL;DR: A novel approach to conceal digital watermark, based on transformation of low-level features of digital images, is proposed, which provides good robustness and fidelity in recover data embedding process and assures the adaptive watermark extraction.

A DCT-based robust image watermarking using local moment
Wen-Chuan Wu,Guang-Ruei Ren +1 more
TL;DR: Experimental results show that the proposed scheme maintains a satisfactory image quality, and the extracted watermark can also have a good accuracy after various attacks, with which the ownership of the image can be still identified.

Gray scale image watermarking using fuzzy entropy and Lagrangian twin SVR in DCT domain
TL;DR: The performance of Lagrangian twin support vector regression (LTSVR), which was successfully applied on synthetic datasets obtained from UCI repository for various kinds of regression problems, is validated by embedding and extracting the watermark on different standard and real world images and verifies the high generalization performance of LTSVR.

Image watermarking based on wavelet hard thresholding
TL;DR: A robust watermarking technique that uses the wavelet based hard thresholding concept for image denoising to determine theWavelet coefficients to be watermarked, which provides better performance under most attacks including JPEG compression.

Wavelet-based method for high-frequency subband watermark embedding
TL;DR: In this article, a wavelet based robust blind watermarking scheme is presented, which embeds the watermark into the wavelet coefficients representative of the image's areas highly dense of details.

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.
