Reseña del libro "A Glance to Digital Image Watermarking Techniques (en Inglés)"

The present work contributes to watermarking protection of digital image copyrights, and more specifically, the integrated methods of digital image watermarking (DIW) represented in recent Iranian publications. For each of the methods, the ultimate goal was to improve the attributes of digital watermark. Given that, several combined or novel watermark embedding techniques were proposed and applied in image blocks. For each of the proposed techniques, the model of watermark embedding and its parameters, as well as decompression and related flaws, the kind of possible attacks on watermarked images, etc. will be mentioned. When to copy electronic data, it is essential to maintain the copyright; therefore, there is not possible easily to do the forgery and manipulation of documents. The watermarking algorithms are proposed as solution for this problem. In this work, a review is represented about a number of proposed algorithms based on different aspects, and then a high yield algorithm is described named one-step Sudoku Table methodology that is more suitable for extracting the image.
