Robust image watermarking based on multiwavelet parent-child relation and adaptive support vector regression
Hamed Ghodrati,Habibolah Danyali +1 more
TL;DR: The proposed robust image watermarking algorithm possesses acceptable perceptual quality, while it is robust against common attacks such as JPEG, low-pass filtering, noise addition, cropping and resizing, etc.

Robust Image Data Hiding Using Geometric Mean Quantization
TL;DR: Simulation results show that this novel quantization based watermarking method has great robustness against common attacks such as AWGN, JPEG and rotation in comparison with recent methods presented so far.

Spatio-Temporal Context Based Adaptive Camcorder Recording Watermarking
TL;DR: Wang et al. as mentioned in this paper proposed a spatio-temporal context based adaptive camcorder recording watermarking scheme (STACR), which is robust to geometric attacks, compression, scaling, transcoding, recoding, and frame rate changes.

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.
Journal ArticleDOI
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.
