Video Watermarking Based on Cloud Model and Geometric Moment
Guo Juan Xu,Jian Jie Li,Jin Lv +2 more
TL;DR: A video watermarking scheme based on geometric moment corrected using the geometric moment’s good characteristic of corrected parameters of scaling attack, and combined with the randomness and fuzziness of Cloud model is proposed.

Watermarking Using Multiresolution Wavelet Transform and Image Fusion
TL;DR: The proposed method for the digital watermarking is based on the multiresolution wavelet transform and the results confirm the superiority of the proposed method on invisibility and robustness.

Zero watermarking scheme for privacy protection in e-Health care
Ayesha Farha Shaik,V. Masilamani +1 more
TL;DR: In this paper , a zero watermarking scheme for privacy protection is proposed which protects the privacy and also eliminates the degradation done during embedding of patient information into the health record.

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.
