摘要
A method of editing a digital image having associated embedded data, such as printing hints, includes embedding (14) a first watermark in the original image (10) before the image is edited (16). The first watermarking scheme associates first watermark information with each pixel and is used to detect which pixels have been edited. A second watermark may be embedded in the original image according to a second watermarking scheme which associates second watermark information with non-overlapping groups of pixels in the original image. The second watermark information may be used to synchronize the first watermark information and to detect editing information which does not change pixel values. After editing, only those edited portions of the image need have their embedded data reapplied. IMAGE
