Orthogonal transform watermarking techniques for authentification of digital images and documents

Orthogonal transform watermarking techniques for authentification of digital images and documents

In our transform-domain-based watermarking algorithms, two-level quantization is employed for both watermark embedding and extraction processes. Our public watermarking method is essentially extended from the semi-private approach and a spread-spectrum (SS) technique, which has been widely used in d...
