Back in the days when Digimarc offered a free personal license for up to 100 images I used to use their digital watermarking. I found that it was quite robust - even after much manipulation the watermark was detectable. One time, just as an exercise, I: o Watermarked an image o Resized and cropped o Printed o Scanned the print (at a different resolution) The resulting image still carried a strong digital watermark! -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
