Content Based Watermarking for Securing Color Images
  DOI :  10.2352/J.ImagingSci.Technol.2005.49.5.art00003  Published OnlineSeptember 2005

In this article a region based color image watermarking algorithm is presented. The objective of the method is to embed a particular message in each region of interest (ROI) in the image. The embedding message has to be detected after image manipulations such as cropping, rotation and color JPEG compression. As a basis for the watermarking, a segmentation algorithm is used. Based on the extracted regions, characteristic features are estimated by using shape information. The embedding message is synchronized with each ROI on each color component Y, Cr and Cb. To embed information non-rounded DCT coefficients are watermarked. Experimental results show the performance of the algorithm against spatial and frequential attacks.
