| 摘 要： | 本文提出了一种子离散小波变换域实现图象水印的方法，其优点是良好的稳健性和层次性的检测方法。这种算法充分利用小波变换的特点，把原始图象和水印分解成多频段的图象来嵌入水印中，检测时，把加了水印的图象塔式分解，通过计算处理每一层取得所有的有关信息。

| Abstract: | This paper presents an image watermarking technology based on disperse wavelet transform. Its exam technique has the advantages of steadiness and layered. The algorithm makes full use of the characteristics of wavelet transform. The original images and watermarks are transformed into a multi - frequency image to be embedded in watermark. In measurement, the watermarked images can be decomposed pyramidally and through calcalating and processing each layer, all the related information can be obtained. |
