提出了一种基于二进小波变换（DYWT）和区间算法（IA）的图像盲水印方法。由于DYWT具有冗余表示，因此水印必须包含的信息量比基于普通离散小波变换的方法要大。我们的水印是一个三元值的标志，通过使用DYWT和IA嵌入到高频组件中。我们描述了基于IA （IDYWT）的DYWT的性质及其计算方法。我们还详细描述了我们的水印过程，并给出了实验结果，表明我们的方法产生的水印图像具有更好的质量，并且对于以下类型的攻击具有鲁棒性：标记，裁剪，中值滤波，对比度调整（MATLAB图像处理工具箱中的histeqanddimadjustcommands），添加高斯白噪声，添加盐和胡椒噪声，JPEG和JPEG2000压缩，旋转，调整大小。
We propose a new blind digital image watermarking method based on the dyadic wavelet transform (DYWT) and interval arithmetic (IA). Because the DYWT has a redundant representation, the amount of information that the watermark must contain is greater than in the case of the methods based on the ordinary discrete wavelet transforms. Our watermark is a ternary-valued logo that is embedded into the high-frequency components through use of the DYWT and IA. We describe the properties of the DYWT based on IA (IDYWT) and its computational method. We also describe our watermarking procedure in detail and present experimental results demonstrating that our method produces watermarked images that have better quality and are robust with respect to attacks on the following types: marking, clipping, median filtering, contrast tuning (histeqandimadjustcommands in the MATLAB Image Processing Toolbox), addition of Gaussian white noise, addition of salt & pepper noise, JPEG and JPEG2000 compressions, rotation, resizing.
