Color Image Watermarking with Watermark Hashing
2019Color images are extensively used, published, and exchanged through internet. The need to establish ownership of digital images has resulted in the development of many image watermarking techniques. Many of these techniques are based on Singular Value Decomposition (SVD) of images.

Proceedings of the 8th workshop on Multimedia and security, 2006
In this paper, we introduce to the special domain of image annotation watermarking, based on embedding of hierarchical data related to objects into user-selected areas on an image. In comparison to earlier methods, the main goal of the work presented here is to provide a specific robustness, specifically against cropping, in a way that preserves ...

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
In this paper we present a reversible watermarking technique for digital images. In our context, reversibility refers to the ability to restore the original image by the watermark detector. The technique is based on a transformation function that introduces 'gaps' in the image histogram. The 'gaps' are used to encode the watermark.

Progressive image watermarking
2000 IEEE International Conference on Multimedia and Expo. ICME2000. Proceedings. Latest Advances in the Fast Changing World of Multimedia (Cat. No.00TH8532), 2002Progressive transmission of images is very useful in many applications, especially in image transmission over the Internet. To view an image, people would want to see part of the image while the image transmission is in progress, rather than having to wait until the end of the image transmission.

Geometric Invariance in Image Watermarking
IEEE Transactions on Image Processing, 2004Surviving geometric attacks in image watermarking is considered to be of great importance. In this paper, the watermark is used in an authentication context. Two solutions are being proposed for such a problem. Both geometric and invariant moments are used in the proposed techniques.

Multichannel watermarking of color images
IEEE Transactions on Circuits and Systems for Video Technology, 2002In the field of image watermarking, research has been mainly focused on grayscale image watermarking, whereas the extension to the color case is usually accomplished by marking the image luminance, or by processing each color channel separately. A DCT domain watermarking technique expressly designed to exploit the peculiarities of color images is ...

Using invisible watermarks to protect visibly watermarked images
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004Physical visible watermarks have been widely used for centuries. Now digital visible watermarks such as electronic logos find their applications in digital library, video broadcasting, and other multimedia services. Several visible watermarking techniques have been proposed in the literature, and meanwhile, some problems with visible watermarks are ...
