Multiplicative Watermark Decoder in Contourlet Domain Using the Normal Inverse Gaussian Distribution
TL;DR: The results show that the proposed watermark decoder is superior to other decoders in terms of providing a lower bit error rate and is highly robust against various kinds of attacks such as noise, rotation, cropping, filtering, and compression.

Temporal synchronization in video watermarking
Eugene T. Lin,Edward J. Delp +1 more
TL;DR: A watermark more resilient against temporal synchronization attacks is designed by adding temporal redundancy in the watermark construction by developing new models for watermark embedding and detection.

A New Statistical Detector for DWT-Based Additive Image Watermarking Using the Gauss–Hermite Expansion
TL;DR: Experimental results demonstrate that the proposed watermark detector performs better than other standard detectors such as the Gaussian and generalized Gaussian, in terms of the probabilities of detection and false alarm as well as the efficacy.

Protecting Fingerprint Data Using Watermarking
TL;DR: This work introduces an application of wavelet-based watermarking method to hide the fingerprint minutiae data in fingerprint images and can also be used to protect the original fingerprint image.

Watermark Compression in Medical Image Watermarking Using Lempel-Ziv-Welch (LZW) Lossless Compression Technique.
TL;DR: This paper focuses on watermarking of ultrasound medical images with Lempel-Ziv-Welch (LZW) lossless-compressed watermarks, which is the combination of defined region of interest (ROI) and imageWatermarking secret key and the performance of the LZW compression technique was compared with other conventional compression methods based on compression ratio.

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.
