Blind forensics of image gamma transformation and its application in splicing detection
TL;DR: The experimental results validate the effectiveness of the proposed detection of image gamma transformation and its application in image splicing detection and are robust to the attack of rank filtering.
Journal ArticleDOI
Watermarking through image geometry change tracking
TL;DR: This paper contributes to the state of the art by proposing an image watermarking technique that attempts to model the attacks like cropping, scaling and rotation in terms of the image geometry.

A New Data Transfer Method via Signal-Rich-Art Code Images Captured by Mobile Devices
Ya-Lin Lee,Wen-Hsiang Tsai +1 more
TL;DR: Good experimental results and a comparison of them with those of an existing alternative method show the feasibility and superiority of the proposed new data transfer method.

Lossless watermarking of compressed media using reversibly decodable packets
TL;DR: A two-way decoding algorithm is capable of resolving and identifying existing resync markers and reestablishing synchronization at the decoder, and has been successfully applied to several MPEG-2 video streams.

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.
