Video Watermarking by using the Wavelet Transform with Perform SVD Technique
T. Harish Kumar,G. Kumaraswamy +1 more
TL;DR: The combination of Discrete Wavelet Transformation (DWT) and Singular Value Decomposition (SVD) of Blue channel is used to embed the watermark, which increases the security, robustness and imperceptibility of the scheme.

Design of an adaptive human visual filter
TL;DR: The design method of a kind of adaptive filters with human visual sensitivity is proposed, which decreases the contradiction between reducing the noise in images and preserving the significant features.

Securing Digital Image with Authentication Code
TL;DR: The authors present a digital image authentication scheme using LSB, keyed hash, and partial encryption and show that the proposed watermarking scheme is secure and efficient in comparison to other related schemes.

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.
