Pattern based robust digital watermarking scheme for images
TL;DR: A transform-domain robust digital watermarking technique which uses a pattern-based compression of the watermark image, an intelligent dynamic embedding of the signature bits and a post-watermarking content-based visual masking technique to deliver high image quality and robustness in retaining watermark content against attacks (cropping).
Proceedings ArticleDOI
A DWT-SVD based digital watermarking technique for copyright protection
TL;DR: Analysis and experimental results show much improved performance of the proposed method in comparison with the pure SVD-based watermarking and the technique without using some wavelet function and Experimental results confirm that the proposed scheme provides good image quality of watermarked images.

Video scene characteristic detection to improve digital watermarking transparency
I.W. Agung,P. Sweeney +1 more
TL;DR: A new method of video scene content characteristic detection is proposed, which can be applied in conjunction with digital watermarking schemes in order to improve the transparency and improve imperceptibility.

Rate-Distortion-Preserving Forensic Watermarking Using Quantization Parameter Variation
Hannes Mareen,Martijn Courteaux,Johan De Praeter,Md. Asikuzzaman,Glenn Van Wallendael,Peter Lambert +5 more
TL;DR: The experimental results prove that the proposed approach retains the rate-distortion performance better than state-of-the-art techniques, and the watermarks are robust to recompression and noise attacks.

An improved wavelet domain digital watermarking for image protection
Dejey,R.S. Rajesh +1 more
TL;DR: A robust, invisible, non-blind watermarking scheme in the wavelet domain is proposed and provides better resistance to collusion attack also when compared with existing spatial domain approach.

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.
