Digital Watermarking Using Fractal Image Coding
A new digital watermark approach based on fractal image coding is proposed in this letter. We present a way to use the fractal code as a means of embedding a watermark. The proposed approach has shown to be resistant to the JPEG lossy compression. Moreover, the digital watermark can be simply extracted from the watermarked image without resorting to the original image. key words: digital waterm...
متن کاملDigital Image Watermarking In DCT Domain
Digital Image watermarking is the process that embeds data called watermark in to multimedia object such that the watermark can be extracted or detected to make an assertion about the object. Watermarking is either “visible” or “invisible”. The growth of high speed computer networks and internets, in particular, explore the means of new business, scientific, entertainment and social opportuniti...
متن کاملCombined DWT-DCT Digital Image Watermarking
The proliferation of digitized media due to the rapid growth of networked multimedia systems, has created an urgent need for copyright enforcement technologies that can protect copyright ownership of multimedia objects. Digital image watermarking is one such technology that has been developed to protect digital images from illegal manipulations. In particular, digital image watermarking algorit...

متن کاملDigital Image Watermarking using BFO Optimized DWT and DCT
Watermarking has been invoked as a tool for the protection of Intellectual Property Rights (IPR) of multimedia contents. Because of their digital nature, multimedia documents can be duplicated, modified, transformed, and diffused very easily. In this context, it is important to develop a system for copyright protection, protection against duplication, and authentication of contents. For this, a...
