摘要： An image is processed to encode a digital watermark, with different regions thereof processed using different levels of watermark intensity. In an image comprised of elements of differing sizes (e.g., halftone shapes of different sizes, or lines of different width), the different regions can be defined by reference to the sizes of elements contained therein. Regions characterized by relatively small elements can be watermarked at a relatively low intensity. Regions characterized by relatively large elements can be watermarked at a relatively high intensity. A variety of other features are also discussed.
摘要翻译： 处理图像以对数字水印进行编码，其中使用不同水平的水印强度处理其不同区域。 在由不同尺寸的元件（例如，不同尺寸的半色调形状或不同宽度的线）组成的图像中，可以通过参考其中包含的元件的尺寸来限定不同的区域。 以相对小的元素为特征的区域可以以相对低的强度加水印。 以相对大的元素为特征的区域可以以相对高的强度加水印。 还讨论了各种其他功能。
