Hybrid domain watermarking technique for copyright protection of images using speech watermarks
TL;DR: A watermarking technique based on various signal processing transforms is proposed and implemented for the security of image using human speech signal and performs better than the existing water marking techniques available in the literature.

A temporal desynchronization resilient video watermarking scheme based on independent component analysis
Jiande Sun,Ju Liu +1 more
TL;DR: Simulations show that this proposed video watermarking scheme is robust not only to temporal desynchronization, e.g., frame swapping, frame dropping, fps conversion, etc, but to most of the common video processing/attacks, E.g. noising, filtering, rescaling, MPEG2-4 transcoding, and intra-video collusion.

Watermarking of ultrasound medical images in teleradiology using compressed watermark.
TL;DR: TDARWMI scheme development to be used for ROI authentication, tamper detection, localization, and lossless recovery was compared and found to be better than other watermarking schemes.

A multi-tier security system (SAIL) for protecting audio signals from malicious exploits
TL;DR: The obtained result ratifies better level protection of audio signals from different security threats and can be recommended for multi channel audio processing.

An image watermarking based on the pdf modeling and quantization effects in the wavelet domain
TL;DR: An image watermarking technique based on the concept of JPEG2000 algorithm is proposed, using biorthogonal wavelet 9/7 transform to provide a set of coefficients suitable for watermark embedding.

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.
