A Study on Spatial and Transform Domain Watermarking Techniques

Genetic watermarking based on transform-domain techniques

An innovative watermarking scheme based on genetic algorithms (GA) in the transform domain is proposed. It is robust against watermarking attacks, which are commonly employed in the literature. In addition, the watermarked image quality is also considered. In this paper, we employ GA for optimizing both the fundamentally con4icting requirements. Watermarking with GA is easy for implementation. ...

A Study on Spatial and Transform Domain

Digital Image Watermarking is used for copyright protection of digital information. With the widespread of internet, the intellectual properties are accessible and manipulated easily. It demanded to have different ways to protect data. Digital watermarking provides a viable and promising solution. In this paper, we have described about the three different watermarking techniques (LSB, DCT, DWT)...

Gabor transform domain watermarking

Transform domain is the most commonly used space for watermarking applications. Most of the common frequency transforms have been used for this purpose. In this work we investigate the use of the Gabor transform in traditional watermarking schemes. A casting method and detection results are thoroughly examined. It seems that traditional detection thresholds are not applicable in this transform,...
