  2. Based on the svs characteristic analysis of image matrix, a visually recognizable binary image watermark is embedded into maximal singular value coefficient in block - based svd transform domain of the cover image. here we brought forward two primary schemes : one need original signal and the other is blind ( without the original cover ). experimental results show that our schemes can extract reliable copy of the hidden watermark from images that have been significantly degraded or altered through several common geometric distortions and signal processing operations

    本文基於圖像矩陣的svd奇異值分解特性分析,提出了在新的svd變換域中進行的數字水印演算法,水印信息嵌入到分塊變換的最大奇異值分量系數中,應用混沌變換加和空域置換,改善了空域性能,安全性高;利用圖像分塊矩陣的奇異值分解穩定性好的特點,採用圖像內容自適應方法算水印的嵌入強,增強了演算法的穩健性;採用二值圖像作為有意義水印進行嵌入和檢測,水印在知上是可的。
