提出了一种基于双树复离散小波变换（DT-CDWT）和区间算法（IA）的数字图像认证水印方法。该方法是一种基于内容的水印方法，它从主图像中生成水印，并通过比较用测试图像构造的两种类型的水印对测试图像进行验证。我们详细描述了我们的水印和认证过程，并给出了实验结果，证明我们的方法可以产生高质量的水印图像，并可以定位被篡改的区域。
We propose a new digital image watermarking method for authentication based on the dual-tree complex discrete wavelet transform (DT-CDWT) and interval arithmetic (IA). This method is a kind of content-based watermarking, because it generates a watermark from the host image and authenticates the test image by comparing two types of watermarks constructed using the test image. We describe our watermarking and authentication procedure in detail and present experimental results demonstrating that our method produces high-quality watermarked images and can locate the areas that have been tampered with.
