|Title:||Orthogonal transform watermarking techniques for authentification of digital images and documents||Authors:||Shu, Feng||Keywords:||DRNTU::Engineering::Electrical and electronic engineering::Electronic systems::Signal processing||Issue Date:||2005||Source:||Shu, F. (2005). Orthogonal transform watermarking techniques for authentification of digital images and documents. Master’s thesis, Nanyang Technological University, Singapore.||Abstract:||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 digital communication, is employed.||URI:||https://hdl.handle.net/10356/3253||DOI:||10.32657/10356/3253||Rights:||Nanyang Technological University||Fulltext Permission:||open||Fulltext Availability:||With Fulltext|
