SYSTEM AND METHOD FOR DIGITAL WATERMARKING |
| 摘要 |
A digital watermarking system and method are disclosed. In one respect, the disclosed digital watermarking includes generating an extracted signal by applying a watermark extractor to an original image, generating a mixed signal by mixing the first signal with a periodic watermark signal using a local weighing factor for the periodic watermark signal that attenuates a strength of the watermark signal in proportion to a pixel luminance level, and replacing the extracted signal in the original image with the mixed signal to generate a marked image, wherein the watermark signal is extractable from the marked image using the watermark extractor. |

1. A digital watermarking method, comprising:
generating an extracted signal by applying a watermark extractor to an original image; generating a mixed signal by mixing the extracted signal with a periodic watermark signal using a local weighing factor for the periodic watermark signal that attenuates a strength of the periodic watermark signal in proportion to a pixel luminance level; and replacing the extracted signal in the original image with the mixed signal to generate a marked image. |
