One common drawback of virtually all current data embedding methods is the fact that the original image is inevitably distorted due to data embedding itself. This distortion typically cannot be removed complet...
The question is raised as to whether or not the currently developed theories of watermarking provide an adequate model for the handling of digital data in the commercial world.
The transmission of any data is always subject to corruption due to errors, but video transmission, because of its real time nature must deal with these errors without retransmission of the corrupted data. The...
Electronic watermarking can be traced back as far as 1954. The last 10 years has seen considerable interest in digital watermarking, due, in large part, to concerns about illegal piracy of copyrighted content....
We present image data hiding and authentication schemes based on halftoning and coordinate projection. The proposed data hiding scheme can embed images of the same size and similar bit depth into the cover ima...
Traditionally, data hiding and compression have had contradictory goals. The former problem adds perceptually irrelevant information in order to embed data, while the latter removes this irrelevancy and redund...
The field of digital watermarking has recently seen numerous articles covering novel techniques, theoretical studies, attacks, and analysis. In this paper, we focus on an emerging application to highlight prac...
Digital watermarking is well known as enabling technology to prove ownership on copyrighted material, detect originators of illegally made copies, monitor the usage of the copyrighted multimedia data and analy...
We present a method (Text-Based Geometric Normalization—TBGN) which, by exploiting the particular content of cartographic images, namely text content, permits to cope with global geometric transformations. Fir...
