Digital video watermarking based on 3D-discrete wavelet transform domain
TL;DR: The proposed DWT (discrete wavelet transform) domain is used for proposed a novel algorithm to place invisible watermark in a video frame based on a three-level DWT using Haar filter that is robust against JPEG compression, geometric attacks, and image processing attacks.

Protection of the patient data against intentional attacks using a hybrid robust watermarking code.
Ahmad Nagm,Mohammed Safy Elwan +1 more
TL;DR: In this paper, a hybrid spatial domain watermarking algorithm that includes encryption, integrity protection, and steganography is proposed to strengthen the information originality based on the authentication, the proposed algorithm checks whether the patient's information has been deliberately changed or not.

TL;DR: The objective of this paper is to evaluate the improvement that channel codes bring to the embedding algorithm.
Dissertation
Image adaptive watermarking using wavelet transform
TL;DR: The main focus of this thesis is to provide good tradeoff between perceptual quality of the watermarked image and its robustness against different attacks and to demonstrate the feasibility of the digital watermarking algorithms for use in multimedia standards.

A Hybrid Fusion Technique for Watermarking Digital Images
TL;DR: Experimental evaluations show that combining the two transforms in this manner offers improved performance in terms of imperceptibility, robustness to jpeg and other kinds of attack on the published (watermarked) image and quality of recovered watermark image than is obtainable using the methods that are based solely on the DWT or DCT techniques or their direct combination.

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.

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.
