Técnica robusta de marca de agua basada en normalización de imágenes
TL;DR: The experimental results show the watermark imperceptibility and robustness against geometric distortion such as rotation, scaling and various other Affine transformation, and common signal processing schemes, such as JPEG compression, Gaussian and impulsive noise contamination.

A blind JPEG image watermarking in the DCT domain
TL;DR: In this article, a blind, low complex, fast, and highly resistant to attacks watermarking algorithm is proposed for JPEG compressed images, which is a discrete cosine transform (DCT) and block based algorithm that adds some Huffman code words to the end of the code sequence of some blocks during JPEG compression procedure.

Multiple Watermarking Scheme for Digital Images
M S Raval,P P Rege +1 more
TL;DR: This work proposes to embed multiple watermarks in a cover image to assist in verifying the integrity of the associated cover image and calls this watermark a “Fragile Water mark” as it is extremely sensitive to any intentional or unintentional change.

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.
