摘　　要：提出了一种基于有限脊波变换域实现图像水印的方法,其优点是良好的稳健性和层次性。这种算法充分利用有限脊波变换的特点,把原始图像和水印分解成多频段的图像来嵌入水印。检测时,把加了水印的图像分解,通过计算处理每一层取得所有的有关信息。This paper presents an image watermarking technology based on finite ridgelet transform. Its advantages is steadiness and layeredness, and the operation law makes full use of the characteristics of finite ridgelet transform. The original images and watermarks are transformed into a multi-frequent image to be embedded in watermark. Being measured, it is subjected to multiresolution decomposition and as a result, all the related information can be obtained.
