This Paper by taking Ruichang paper-cut images as an example and by binarization image edge spatial watermarking algorithm and combining with QR code authentication technology, transforms text authentication information into QR code image and hides QR code image in edge of Paper-cutting image as watermark and finally places QR code authentication information in blank area of the paper-cut imagespatial watermark. In this way, invisible edge spatial watermark and visible QR code form double authentication protection for paper-cut images and provides a kind of effective method for copyright protection of paper-cut digital images.  a9781450353663 (ISBN)
