Watermarking method with print-scan compensation
Abstract:
A digital watermark may be applied to digital image data to produce watermarked digital image data. A transformation may be applied to the watermarked digital image data to produce transformed watermarked digital image data. The transformation may approximate the inverse of a transformation that represents distortion caused by transmission through a print-scan channel.
Abstract(Chinese):

数字水印可以应用于数字图像数据以产生水印的数字图像数据。 可以将变换应用于水印数字图像数据，以产生经变换的水印数字图像数据。 该变换可以近似表示通过打印扫描通道的传输引起的失真的变换的逆。
