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 semi-blind digital watermarking scheme based on singular value decomposition
TL;DR: This paper presents a robust watermarking approach for hiding grayscale watermarks into digital images by plugging the codebook concept into the singular value decomposition (SVD) and embeds the singular values of the original image into the watermark one to attain the lossless objective.

A Review of Medical Image Watermarking Requirements for Teleradiology
TL;DR: The security requirements of medical images as well as expected threats in teleradiology are reviewed and justification for watermarking over conventional security measures is made in terms of their various objectives, properties, and requirements.

Multichannel watermarking of color images
TL;DR: A new approach to threshold selection is proposed, which permits reducing the probability of missed detection to a minimum, while ensuring a given false detection probability, with respect to existing grayscale algorithms.

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.
