摘要

本文介绍了一种基于混沌和快速曲线变换的方法。首先用阿诺德变换对水印进行置乱。然后利用切比雪夫混沌序列对数字水印进行混沌加密。最后，将经过混沌处理的水印图像嵌入到经过快速曲线变换的图像中频系数中。水印的提取是水印嵌入的逆处理。

A kind of image watermarking algorithm based on chaos sequences and fast curvelet transform

This paper introduces a kind of method based on chaos and fast curvelet transform. At first, the watermark is done the scrambling by the Arnold transform. Then the digital wartermarking is done the chaos encryption by the chebyshev chaos sequences. At last, the watermarking image that has been done the chaos processing is embedded into the intermediate frequency coefficient of image that has been done the fast curvelet transform. The extraction of watermark is the inverse processing of the embedding of watermark.
