| Outline of Final Research Achievements |
This study focuses on digital watermarking via spread codes in communication theory and filters in signal processing theory. Main contributions of this work are three-fold: 1) a watermarking scheme based on combined complex transforms, 2) an image watermarking technique via highpass filtering, and 3) a robust watermarking scheme based on frequency selective watermark. I presented the aforementioned approaches and demonstrated their validity.
