    摘要: A method and system is disclosed for printing an authenticatable image having an embedded image into a receiver having a discernible physical characteristic, such that the printed image can be used to authenticate the receiver which includes scanning the receiver to produce information related to the discernible physical characteristic of the receiver, and providing a carrier which includes information related to the scanned receiver discernible physical characteristic. The method also includes combining the carrier with an input image to form the authenticatable image having the embedded image, and printing the authenticatable image having the embedded image onto the receiver.

    摘要: A method for caries detection uses an image capture device (30, 32) to obtain fluorescence image data from the tooth (20) by illuminating the tooth to excite fluorescent emission. A first enhanced image of the tooth is then obtained by illuminating the tooth at a first incident angle, obtaining a back-scattered reflectance image data from the tooth tissue, and combining the back-scattered reflectance image data with the fluorescence image data. A second enhanced image of the tooth is then obtained by illuminating the tooth at a second incident angle, obtaining a back-scattered reflectance image data from the tooth tissue, and combining the back-scattered reflectance image data with the fluorescence image data. The first and second enhanced images are then analyzed to select and display the best-contrast image. This method provides high contrast images for carious regions (58) on all tooth surfaces.
