COX proposed a DCT-domain spread spectrum watermarking embedding algorithm, which is a non-blind watermarking approach that can serve as a foundation for developing blind watermarking algorithms through subsequent improvements.
This program simulates a digital watermarking algorithm resistant to print-scan attacks, utilizing DCT-domain data classification for effective performance. The underlying principles are based on the reference book "Digital Watermarking Theory and Technology" edited by Yang Yixian et al., published by Higher Education Press. The implementation involves discrete cosine transform (DCT) coefficient manipulation and classification-based embedding strategies.
