Reversible video watermarking based on histogram modification of motion compansated prediction error
İbrahim Yildirim,Cabir Vural +1 more
TL;DR: This paper investigates the influence of the occlusion in a reversible video watermarking technique based on histogram modification of motion compensated prediction error and presents a new reversible videoWatermarking algorithm that has a better performance in occluded areas.

Reversible data embedding in Golomb-Rice code
TL;DR: A generic reversible data embedding method that is applicable in any bitstream consists of GRC (Golomb-Rice code) with the ability to remove, extract, re-write, control accessibility and secure the payload without decoding the original image.

Digital watermarking : An approach based on Hilbert transform
TL;DR: This paper proposes an algorithm for embedding and extracting watermark in a host image and analytically obtain a parameter related to this procedure and shows that the algorithm performs well even if the host image is corrupted by various attacks.
Proceedings ArticleDOI
Performance comparison of wavelet filters against signal processing attacks
TL;DR: This algorithm combines the advantages and removes the disadvantages of these two transforms techniques and provides robust watermark without degradation of image quality.

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.
