Abstract
In this paper we present a new near lossless reversible watermarking algorithm using adaptive prediction for embedding. The prediction is based on directional first-order differences of pixel intensities within a suitably selected neighborhood. The proposed scheme results to be computationally efficient and allows achieving high embedding capacity while preserving a high image quality. Extensive experimental results demonstrate the effectiveness of the proposed approach. © 2010 IEEE.File in questo prodotto:
