Summary:
伴隨著個人電腦與網際網路的普及,以及數位化的趨勢,如何保護數位多媒體的智慧財產權是一個重要的問題。數位浮水印技術提供了一個有效的解決方法以保護數位多媒體的著作權。本論文提出一個結合離散餘弦轉換與奇異值分解之浮水印技術,並且透過多目標基因演算法對數位浮水印技術進行最佳化。使用者可以從多目標基因演算法產生的解集合中挑選理想的最佳解,如此可滿足需求不同的使用者;另外,相較於單目標基因演算法,多目標基因演算法所求得的解集合穩定性更高。實驗結果證實,我們的方法所產生的浮水印不僅具有高抗攻擊性,亦具有良好的影像品質,並且較單目標最佳化式浮水印演算法穩定性更高、應用度更廣。 With the trend of digitalization, the popularization of personal computer, and Internet, an important issue should be considered that is how to protect the multimedia files from illegal use. Digital watermarking is an effective solution for protecting the copyright of multimedia files. In this paper, we proposed a DCT-SVD-based watermarking algorithm, and we optimized the algorithm through a multi-objective genetic algorithm (MOGA). The user can choose one optimal solution from the solution set according to the demand of user. Furthermore, the solutions obtained from MOGA are more stable than those from a single-objective genetic algorithm (SGA). Experimental results show that the proposed approach has batter robustness as well as better image quality, and the proposed approach is more stable than SGA.
