Error correcting codes for robust color wavelet watermarking

Error correcting codes for robust color wavelet watermarking

This article details the conception, design, development and analysis of invisible, blind and robust color image watermarking algorithms based on the wavelet transform. Using error correcting codes, the watermarking algorithms are designed to be robust against intentional or unintentional attacks such as JPEG compression, additive white Gaussian noise, low pass filter and color attacks (hue, sa...

Optimization of Watermarking Performances Using Error Correcting Codes and Repetition

With the ever increasing development and usage of digital technologies and digital data the question of protecting intellectual property of digi tal data has becoming more and more important Digital watermarking which allows to embed copyright information into the digital data has become more and more indispensable Due to its characteristics one of the problems in digital watermarking for xed i...

A Robust Wavelet Based Watermarking System for Color Video

In this paper, we propose a wavelet based watermarking system. The system uses wavelet transform for red, green and blues channel independently. We use space-time coding for encoding the watermark message before data embedding. The bit-error-rate of the recovered message is calculated. The embedding factor is selected in such a way that the host video maintains the same quality with/without usi...

Synchronizable Error-Correcting Codes

A new technique for correcting synchronization errors in the transmission of discrete-symbol information is developed. The technique can be applied to any t-additive-error-correcting Bose-Chaudhuri-Hocquenghem code, to provide protection against synchronization errors. The synchronization error is corrected at the first complete received word after the word containing the synchronization error,...
