全面系統(tǒng)地研究了水印信號的處理技術(shù)數(shù)字水印技術(shù)除了水印嵌入和提取的算法外，還有許多工作需要做，如水印的選碼、編碼、調(diào)制、解調(diào)、能量的確定等等，這些預(yù)處理和后處理工作是算法有效實施的必要保證，正是基于這樣的認識，本文利用較大的篇幅對水印的基本理論知識進行了詳細的分析和研究，在水印的調(diào)制方面，提出了混沌調(diào)制法；在圖像水印的置亂方面，提出了混沌置亂法；在文字水印的處理上，引入了bch編碼；在水印容量分析方面，結(jié)合現(xiàn)代通信理論，對圖像在dct域和小波域內(nèi)的水印容量估算進行了詳細的探討，這些工作不僅為本文后期工作鋪平了道路，而且對數(shù)字水印的研究具有重要的意義。 - It's difficult to find approximate estimate in a sentence. 用approximate estimate造句挺難的
