During the latest 20 years, great progress has been made in the theory, method and technology of image - compression coding on the basis of such traditional coding methods as coding forecast and exchanger coding etc ; wavelet transformation has been widely used in signal - disposal field, because it has a characteristic of energy focus, it puts forwards a concept of multi - resolution ration analysis and the realization o f algorithm about wavelet decompose and fast rebuild. among the applications of wavelet analysis, it is rather mature to apply it to image - data compressing
近20年來,在預測編碼、變換編碼和其它傳統編碼方法的基礎上,圖像壓縮編碼的理論、方法和技術取得了較大進展;其中小波編碼演算法因其能量集中特性、多分辨分析概念的提出和小波分解與重構快速演算法的實現,使得小波變換在信號處理領域得到了廣泛的應用,小波分析應用於圖像數據壓縮是小波分析應用的一個比較成熟的方面。Wavelets are becoming a key technique in the ongoing source compression standard jpeg - 2000. the positive arguments for advocating dwt in image watermarking are : preventing watermark removal by jpeg - 2000 lossy compression, reusing previous studies on source coding regarding the visibility of image degradations, and offering the possibility of embedding in the compressed domain
在小波域嵌入水印的原因是:可以防止由於jpeg - 2000有損壓縮而造成的水印消除;可以利用信源編碼領域對圖像失真的可見性研究成果控制水印的嵌入位置和強度;可以實現在壓縮域直接嵌入水印。
