Автор:Emad E.

Watermarking refers to the process of adding a structure called a watermark to an original data object. Such a watermark can be used for several purposes including copyright protection, fingerprinting, copy protection, broadcast monitoring, data authentication, indexing, and medical safety. This book presented robust watermarking algorithms for 2D images, 3D models, and video image sequences. We have demonstrated the use of these algorithms in multimedia copyright protection. The objective was to embed information about the owner of the data in order to prevent other parties from claiming the copyright on that data. We have verified the effectiveness of the proposed methods through experimental results with a variety of 2D images, 3D models, and video image...
