Segmentation and Content-Based Watermarking for Color Image and Image Region Indexing and Retrieval

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
In this paper, an entirely novel approach to image indexing is presented using content-based watermarking. The proposed system uses color image segmentation and watermarking in order to facilitate content-based indexing, retrieval and manipulation of ...
