A Blind Reversible Data Hiding Method for High Dynamic Range Images Taking Advantage of Sparse Histogram
Masaaki Fujiyoshi,Hitoshi Kiya +1 more
TL;DR: While an RDH method generally needs to memorize a set of image-dependent parameters for hidden data extraction and original image recovery, the proposed method is free from parameter memorization by introducing two mechanisms; restriction of histogram modification and parameter hiding prior to data hiding.

Complexity-scalable compensation of geometrical distortions in image watermarking
TL;DR: This paper presents an efficient method for inverting geometrical distortions that may spatially desynchronise a watermark detector using an orthogonal polynomial mapping, which is efficiently scalable in complexity.

Content segmentation of watermarking
TL;DR: In this paper, the authors proposed a method for providing a data stream comprising a plurality of content elements, where at least one of two or more copies of a first content element of the data stream has been watermarked with a different watermark.

A New Pre-processing Approach to Improve DCT-Based Watermarkings Extraction
TL;DR: Experimental results show that extraction performance of DCT-based watermarking algorithm is improved by applying the proposed pre-processing scheme before watermark extraction procedure.

An Image Watermarking Method using the Lifting Wavelet Transform
Akio Miyazaki,F. Uchiyama +1 more
TL;DR: This paper proposes a new watermarking method for images using the lifting wavelet transform that can divide watermarked content into watermark and original content perfectly after watermark detection, and realizes digital watermarks for multimedia contents like medical images, electric documents, computer programs, and data.

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.
