A new reversible video watermarking method based on motion compensated interpolation

Digital watermarking can be defined as embedding information into digital signals. Original signal is distorted as a result of watermarking. The goal in reversible watermaking is to reconstruct the original signal from the watermarked signal without error. In this study a new reversible watermaking algorithm based on motion compensated interpolation error is developed for digital video. The method not only provides high capacity but also creates negligible distortion in the original signal. The method is shown to be superior to the existing algorithms in terms of capacity and image quality by means of computer simulations.
