Implementation of Adaptive Unsharp Masking as a pre-filtering method for watermark detection and extraction [PDF]

open access: yes, 2016
Digital watermarking has been one of the focal points of research interests in order to provide multimedia security in the last decade. Watermark data, belonging to the user, are embedded on an original work such as text, audio, image, and video and thus,

Foveated image watermarking [PDF]

open access: yesProceedings. International Conference on Image Processing, 2003
The spatial resolution of the human visual system (HVS) decreases rapidly away from the point of fixation (foveation point). By exploiting this fact, we propose a watermarking approach that embeds the watermark energy into the image periphery according to foveation-based HVS contrast thresholds.

Partition clustering for GIS map data protection [PDF]

open access: yes, 2014
One of the main research issues of digital data is defined by copyright protection, and digital watermarking is a potential solution to this issue. While there is an abundance of research on digital watermarking for image data, there is far less research

A contrast-sensitive reversible visible image watermarking technique [PDF]

open access: yes, 2009
A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme is proposed to satisfy the applications, in which the visible watermark is expected to combat copyright piracy but can be removed to losslessly recover the ...

Reversible watermarking scheme with image-independent embedding capacity [PDF]

open access: yes, 2005
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,
