Robust Adaptive Image Watermarking using Visual Models in ...
Robust Adaptive Image Watermarking using Visual Models in DWT and DCT Domain: Ahmed A. Abdulfetah, Xingming Sun, Hengfu Yang and Nur Mohammad: Abstract: In this study, two image adaptive invisible digital watermarking algorithms based on DWT and DCT are proposed for copyright protection. The first proposed algorithm utilizes Watson’s visual ......
Image-adaptive watermarking using visual models - IEEE ...
Image-adaptive watermarking using visual models ... while being extremely robust to attack. For instance, in the case of image data, editing the picture or illegal tampering should not destroy or transform the watermark into another valid signature. ... We propose two watermarking techniques for digital images that are based on utilizing visual ......
An adaptive color image watermarking using RDWT-SVD and ...
Existing watermarking schemes use either a binary or grayscale image as a watermark. This paper proposes a new robust and adaptive watermarking scheme in which both the host and watermark are the color images of the same size and dimension. The security of the proposed watermarking scheme is enhanced by scrambling both color host and watermark ......

An Effective Image-Adaptive Hybrid Watermarking Scheme ...
Image-adaptive nature of the scheme is reflected in the usage of only high entropy 8 × 8 blocks for the watermark embedding. Binary watermark is embedded in the DCT coefficients using a flexible strength derived from the means of the DCT coefficients.
A robust semi-blind watermarking for color images based on ...
In this paper, a robust semi-blind watermarking scheme for color images, based on multiple decompositions is proposed to preserve the copyrights of the owner. Using multiple decompositions, the gray watermark is embedded into a host color image. Prior to that, to enhance security the gray watermark is encrypted with Arnold transform and SVD by generating secret keys....
Image-adaptive Watermarking Using Visual ... - CiteSeerX
In this paper, we describe digital image watermarking techniques, known as perceptually based watermarks, that are designed to exploit aspects of the human visual system. In the most general sense, any watermarking technique that attempts to incorporate an invisible mark into an image is perceptually based.

Multipurpose Watermarking Algorithm for Medical Images
Considering the existing medical image watermarking algorithms, a single function often has limitations, and a multipurpose watermarking algorithm for medical images is proposed. First, medical images are divided into regions of interest (ROIs) and regions of noninterest (RONIs). Then, the authentication watermark produced for each subblock of the ROI is embedded into the corresponding mapping ...
Image adaptive watermarking using wavelet domain singular ...
Abstract: In this letter, we propose a novel, yet simple, image-adaptive watermarking scheme for image authentication by applying a simple quantization-index-modulation process on wavelet domain singular value decomposition. Unlike the traditional wavelet-based watermarking schemes where the watermark bits are embedded directly on the wavelet coefficients, the proposed scheme is based on bit ......
