Rate distortion optimization for efficient watermarking in the DCT domain
TL;DR: By integrating the rate-distortion optimization method with the watermarking process, this work can control the rate of the watermarked image with minimum additional distortion.

Optimization of Watermarking Performances Using Error Correcting Codes and Repetition
TL;DR: Different ways of applying error correcting codes, repetition and some combinations of the two are investigated, given different capacities of a fixed image for different error rates of the watermarking channel, in order to obtain optimal selection for a given length of signature.

A Framework for Iris Biometrics Protection: A Marriage Between Watermarking and Visual Cryptography
TL;DR: The experimental and comparison results on the CASIA V4 and UBIRIS V1 iris databases demonstrate that the proposed framework preserves the privacy of the iris images and templates and retains robustness to malicious attacks, while it does not have a discernible effect on the recognition performance.

Digital Watermarking in Video for Copyright Protection
Anita Jadhav,Megha Kolhekar +1 more
TL;DR: This paper proposes dynamic size 3D-DCT technique (by "scene change detection") for embedding binary/ gray scale/ color watermark on a color digital video and compares the results with existing fixed length 3 D DCT technique.

Hybrid DWT-SVD video watermarking
TL;DR: An effective, robust, and imperceptible video watermarking algorithm is proposed by virtue of applying a cascade of two powerful mathematical transforms; the discrete wavelets transform (DWT) and the singular value decomposition (SVD).

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.
Journal ArticleDOI
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.
Proceedings ArticleDOI
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.
Journal ArticleDOI
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.
