Abstract

The resistance of watermarking schemes against geometric distortions has been the subject of much research and development effort in the last 10 years. This is due to the fact that even the minor geometric, manipulation of the watermarked image can dramatically reduce the ability of the watermark detector to detect the watermark, that is, the watermark detector can lose the synchronization. By this, the watermark synchronization can be defined as a process for finding the location for watermark embedding and detection. A variety of techniques have been proposed to provide partial robustness against geometrical distortions. These techniques can be divided into two groups: (1) techniques that use the original image to recover to synchronization and (2) techniques that do not have the access to the original image content during the synchronization process. This chapter classifies and analyzes techniques and approaches that are currently used in watermarking schemes to recover the synchronization.
