Expansion Embedding Techniques for Reversible Watermarking
D.M. Thodi,Jeffrey J. Rodriguez +1 more
TL;DR: The experimental results for many standard test images show that prediction-error expansion doubles the maximum embedding capacity when compared to difference expansion, and there is a significant improvement in the quality of the watermarked image, especially at moderate embedding capacities.
Proceedings ArticleDOI
Prediction-error based reversible watermarking
D.M. Thodi,Jeffrey J. Rodriguez +1 more
TL;DR: This work proposes a new reversible watermarking algorithm that exploits the redundancy in the image to achieve very high data embedding rates while keeping the resulting distortion low.
Proceedings ArticleDOI
Reversible watermarking by prediction-error expansion
D.M. Thodi,Jeffrey J. Rodriguez +1 more
TL;DR: A new reversible (lossless) watermarking algorithm for digital images that exploits the inherent correlation among the adjacent pixels in an image region using a predictor to embed a large payload while keeping the distortion low.
