A Multiresolution Watermark for Digital Images
, 1997
"... In this paper# weintroduce a new multiresolution water# marking method for digital images. The method is based on the discrete wavelet transform #DWT#. Pseudo#random codes are added to the large coe#cients at the high and middle frequency bands of the DWT of an image. It is shown that this method is ..."

Attacks Analysis for Keyed Blind Multiresolution Watermarking Algorithm
"... Abstract:- This paper presents noise and compression attacks results for a blind multiresolution watermarking scheme based on a modified Xia's algorithm. The results are based on Levels 2, 5 and 8 of a DWT scheme at different scale factors (α) used in the watermark insertion. Key- Words:- Blind ..."

Extraction of Multiresolution Watermark Images for Resolving Rightful Ownership
- In Proc. IS&T/SPIE Symposium on Electronic Imaging: Security and Watermarking of Multimedia Contents
, 1999
"... Digital watermarking has been recently proposed as the mean for intellectual property right protection of multimedia data. We present some ways to "visualize" the invisible watermarks, both statistically and perceptually, for proving the ownership. A system which is capable of embedding a ..."

the false alarm detection probability should be considered as a fundamental measure for a valid ownership claim, the ability to extract a meaningful watermark image will greatly facilitate the process of convincing the jury of an ownership claim. Keywords: multiresolution watermark, scalable visual
Digital Image Multiresolution Watermark Based on Human Visual System Using Error Correcting Code
"... Digital watermarking has been proposed as a way to claim protection. In this paper, we try to use the error-correcting code skill, the multiresolution of wavelet transformation, and the human visual system to improve the traditional watermarking. Error-correcting based watermarking will have the pro ..."

Multiresolution scene-based video watermarking using perceptual models
- IEEE Journal on Selected Areas in Communications
, 1998
"... Abstract — We present a watermarking procedure to embed copyright protection into digital video. Our watermarking procedure is scene-based and video dependent. It directly exploits spatial masking, frequency masking, and temporal properties to embed an invisible and robust watermark. The watermark c ..."

to thwart unauthorized removal. Furthermore, the author representation resolves the deadlock problem. The multiresolution watermark may be detected on single frames without knowledge of the location of the frames in the video scene. We demonstrate the robustness of the watermarking procedure to several
Digital watermarking using multiresolution wavelet decomposition
, 1998
"... We present a novel technique for the digital watermarking of still images based on the concept of multiresolution wavelet fusion. The algorithm is robust to a variety of signal distortions. The original unmarked image is not required for watermark extraction. We provide analysis to describe the beha ..."

Watermarking by Multi-resolution Hadamard Transform
- In: Proceedings of the European Conference on Electronic Imaging & Visual Arts (EVA2001), Mar 26-30
, 2001
"... In this paper a watermarking algorithm for digital images is presented. The method operates in the multi-resolution Hadamard transform domain. The watermark is constructed as a normally distributed random vector and is inserted into the perceptually most significant spectral components of the image. ..."
