Perceptual Metrics Watermarking - An Effective Algorithm With Retrieval Systems
Assessing and comparing the performance of watermarking algorithms is difficult. The visibility of the watermark is an important aspect in this process. The ease in which digital data can be manipulated has created a need for techniques that determine the credibility of digital information. In the recent development of digital multimedia in an entire range of the everyday life has brought forth two active areas of research, namely, retrieval systems and watermarking technology. The problem of associating messages to multimedia content can be addressed by a watermarking system which embeds the associated messages into the multimedia content (also called Works). A drawback of watermarking is that the content will be distorted during embedding.
