Content-based Watermarking for Indexing Using Robust Segmentation

By Nikolaos Boulgouris Ioannis, Ioannis Kompatsiaris, Vasileios Mezaris and Michael G. Strintzis


In this paper, a novel approach to image indexing is presented using content-based watermarking. Some concepts associated with the application of watermarking to image indexing are discussed and a segmentation algorithm, appropriate for content-based watermarking, is presented. The segmentation algorithm is applied on reduced images and derives the exact same objects when performed on either the original or the watermarked image. In this way, the proposed system does not suffer from synchronization problems that usually occur during watermark detection.
