A Comparative Analysis of Wavelet Families for Invisible Image Embedding
TL;DR: The performance of wavelet functions, viz., Haar, Daubechies, symmetric, and biorthogonal for invisible image embedding is analyzed and the embedding and extraction processes are deployed using the number theory concept of embedding.

An Analytical Framework for Comparative Analysis of Various Watermarking and Steganographic Techniques
TL;DR: This paper presents a framework for analyzing and evaluating the strengths of various watermarking algorithms and focuses exclusively on the analysis of water marking of digital images.

The Potential Impact of Video Manipulation and Fraudulent Simulation Technology on Political Stability
TL;DR: In this paper, video manipulation and fraudulent simulation technology combines facial recognition with a neural network to allow its users to create fake impersonations of public figures, leading to a rise in incidents stemming from fake news, imitation of authority, and plausible deniability.

Digital image watermarking by using intermediate significant bits in gray scale images
TL;DR: The proposed method aims to embed watermark in different bit planes of host image which can improve both the visual quality and robustness, and a Zig-zag algorithm is also recommended to change the order of embedding in watermarked image.

Effects of JPEG Compression on Reading Optical Watermarking Embedded by Using Color-Difference Modulation
TL;DR: The simulation results showed that the accuracy in reading out embedded information decreases when captured images are compressed, however, for medium-level or low compression rates 100% accuracy can be expected by using the error correction technique.

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.
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.
