Abstract

A digital watermark is an invisible mark embedded in a digital image which may be used for copyright protection. This paper proposes that Fourier-Mellin transform-based invariants can be used for digital image watermarking. The embedded marks may be designed to be unaffected by any combination of rotation, scale and translation transformations. The original image is not required for extracting the embedded mark.
旋转、缩放和平移不变数字图像水印
数字水印是嵌入在数字图像中的不可见标记,可用于版权保护。提出了基于Fourier-Mellin变换的不变量可用于数字图像水印。嵌入的标记可以被设计成不受旋转、缩放和平移变换的任何组合的影响。提取嵌入标记不需要原始图像。
