dc.description.abstract | 資訊的數位化使得數位內容保護版權保護受到重視,數位浮水印技術的發展提供一種數位權利保護方法。數位浮水印須同時具備透明度、安全性、明確性、強韌性、容量及不需來源比對等的要求,能夠承受來自外在的幾何攻擊、壓縮攻擊等惡意破壞。本研究以小波轉換理論為基礎,以均勻量化方法將數位浮水印嵌於由中頻係數組成之小波樹中。而小波樹之量化,則是在不影響圖形品質之下決定之。此外,本研究提出小波濾波器組選擇原則,適用的filter bank將對於解浮水印有正面的幫助。而本研究提出之均勻Deadzone Scalar Quantization的方法,使以小波樹為基礎之浮水印演算法有更高的強韌性,在數位智財權的保護上提供更有效的技術。 | zh_TW |
