A Robust Image Watermarking Using Two Level DCT and Wavelet Packets Denoising
TL;DR: This paper presents a blind low frequency watermarking scheme on gray level images, which is based on DCT transform and spread spectrum communications technique and proves to be highly resistant in cases of compression and additive noise, while preserving high PSNR for the watermarked images.

Analysis and comparison of holographic and traditional digital image watermarking in DWT domain
TL;DR: Test results show that the hidden images of holographic water marking survive geometric distortion more than the traditional one, especially cropping, and the Gaussian filter, Gaussian noise and JPEG compress resilient properties of traditional watermarking are a little better than the holographicWatermarking.

An Industrial Watermarking Process for Plastic Card Supports
TL;DR: This paper investigates a robust method to watermark and decode images such as identity pictures printed on plastic card supports that have a special interest in industrial areas requiring secure authentication.

Blind Watermarking of Color Images Using Karhunen–Loève Transform Keying
TL;DR: The proposed scheme performs a decorrelation of the RGB color bands of the image to be watermarked using a Karhunen–Loeve transform, then marks the coefficients of the KLT of the first band obtained, maintaining at the same time a high image quality.

An image watermarking method based on the singular value decomposition and the wavelet transform
R.B. Dili,Elijah Mwangi +1 more
TL;DR: A robust image watermarking scheme in which a binary image is embedded in the singular values of selected DWT blocks in the horizontal and vertical sub-bands of a 1-level decomposition of a gray-scale image is proposed.

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.
