A New Digital Watermarking Algorithm Using Combination of Least Significant Bit (LSB) and Inverse Bit

open access: yes, 2011
In this paper, we introduce a new digital watermarking algorithm using least significant bit (LSB). LSB is used because of its little effect on the image.

An Approximate Schur Decomposition-Based Spatial Domain Color Image Watermarking Method

open access: yesIEEE Access, 2019
In this paper, an approximate Schur decomposition-based spatial domain blind color image watermarking method is proposed to protect the copyright of color images, which has low computation complexity similiar to the watermarking technique in the spatial ...

Wavelet-based digital image watermarking

open access: yesOptics Express, 1998
A wavelet-based watermark casting scheme and a blind watermark retrieval technique are investigated in this research. An adaptive watermark casting method is developed to first determine significant wavelet subbands and then select a couple of significant wavelet coefficients in these subbands to embed watermarks.

Document image watermarking

open access: yes, 2006
64 p. This document provides a design concept of document watermarking software which is implemented in Matlab. The basic concept and foundation of our watermarking strategy is pixel flipping based on Curvature-Weighted Distance Difference (CWDD) measure.

Segmentation and Content-Based Watermarking for Color Image and Image Region Indexing and Retrieval

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
In this paper, an entirely novel approach to image indexing is presented using content-based watermarking. The proposed system uses color image segmentation and watermarking in order to facilitate content-based indexing, retrieval and manipulation of ...
