| 摘 要： | 该文提出一种基于Turbo码的自适应水印算法。为了实现自适应嵌入水印,将原始图像分块并利用视觉掩蔽特性对图像块进行分类,根据分类的结果,将不同强度的水印分量嵌入到图像块的DCT低频系数中。实验结果表明,利用该算法实现的水印具有很好的视觉掩蔽效应和鲁棒性。

| Abstract: | In this paper,an adaptive image watermarking algorithm in DCT domain based on Turbo Code is proposed.By exploiting the visual masking features of HVS,the algorithm splits the original image into blocks and classifies these blocks.Watermark components with different strength are inserted into some low -frequency coefficients adaptively according to the classification.The experimental results demonstrate that the watermarks generated with the proposed algorithm are perceptually invisible and robust against noise. |
