基于混沌的DCT域数字水印技术研究

Study on DCT Region Digital Watermarking Technology Based on Chaos in Maths

通过对基于混沌的DCT域数字水印技术在图像生成、水印嵌入、水印提取以及对水印攻击实验的结果分析中可以看出,此技术满足信息时代信息化所要求的数字图像信息隐藏的需要。

It studies the DCT region digital watermarking from the perspectives of image generation,embedding of watermark,recovering of watermark and experiments to test its stability.The result shows that this technology fit for the requirement of digital image hiding technology needed in the informational and technological age.
