Robust Adaptive Image Watermarking using Visual Models in ...
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 model (JND) to determine the watermarking strength necessary to invisibly embed the watermark in the DCT block coefficients of the cover image by ......

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 ...
