Reversible watermarking algorithm based on prediction error expansion for color image

2017 32nd Youth Academic Annual Conference of Chinese Association of Automation (YAC), 2017
A reversible watermarking algorithm in low distortion is proposed for color images in this paper. Through analyzing the correlation of different color components in color image, and expanding prediction pixels by adaptive prediction operator, the embedding of watermark data and the retrieving of the original image are realized.

Reversible watermarking of 3D mesh models using prediction-error expansion

2010 3rd International Congress on Image and Signal Processing, 2010
A reversible watermarking scheme for 3D meshes based on prediction-error expansion is proposed in this paper. In our algorithm, we embed the watermark by slightly changing the positions of some vertices in the mesh model. For a vertex to be altered for embedding, the centroid of its adjacent vertices is calculated as datum position which is kept ...

Reversible Watermarking Based on Prediction-Error Expansion for 2D Vector Maps

2013
In order to increase the embedding capacity when one hides information in 2D vector maps in a reversible way, researchers present a novel algorithm based on prediction-error expansion. In two neighboring coordinate values, researchers use the latter as the predicted value of the former. The difference between the original value and the predicted one is
