本章沿着介绍了空间域和变换域水印的主要技术，以及水印算法的主要性能参数，如峰值信噪比（PSNR）、加权峰值信噪比（WPSNR）、均方误差（MSE）、通用图像质量指标、结构相似性指标测度（SSIM）、归一化相关性（NC）、噪声可见性函数（NVF）和误码率（BER）。任何水印算法的一个重要方面是其对攻击的鲁棒性。近年来，一些标准的基准测试工具可用于检测水印算法的鲁棒性。此外，本章介绍了不同类型的攻击和基准工具的医学图像水印的概述。
This chapter presents the important techniques of watermarking in spatial and transform domains along with major performance parameters such as peak signal to noise ratio (PSNR),weighted peak signal-to-noise ratio(WPSNR), mean square error (MSE), universal image quality index, structural similarity index measure (SSIM), normalized correlation (NC),noise visibility function (NVF)and bit error rate (BER) of the watermark algorithm. An important aspect of any watermarking algorithm is its robustness against attacks. Recently, some standard benchmark tools are available to determine the robustness of watermarking algorithm. Further, the chapter introduces an overview of different types of attacks and benchmark tools for medical image watermarking.
