HALFTONE WATERMARKING AND RELATED APPLICATIONS
3/28/2006 12:00:00 AM
Digital watermark embedding is incorporated into processes for generating halftone images. In a halftone process using a halftone screen, the halftone screen is used to determine the geometric distortion of an image. After determining the geometric distortion, a watermark decoder compensates for this distortion and retrieves an embedded digital watermark.
