摘要： A digital image processing method includes the steps of embedding a delta function in a digital image; subjecting the digital image to an intermediate processing step, the intermediate processing step having a modulation transfer function (MTF) that blurs the image; extracting the delta function from the processed digital image; and estimating the MTF from the recovered delta function. The blur is removed from the image by generating a sharpening filter that is substantially the inverse of the MTF and applying the sharpening filter to the blurred image to produce an improved image.

摘要： A method 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 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： Apparatus for embedding information in a digital image digitized from a developed photographic film in response to a film property and information to be embedded into the digital image includes a scanner for scanning the image on the developed photographic film to produce the digital image. The apparatus stores the film property and has input circuitry for storing information associated with the image and to be embedded in the digital image. The apparatus responds to the stored the film property and the associated information for modifying a predetermined number of pixel values with the associated information in the digital image so that the associated information is embedded in the digital image, wherein the embedded information can subsequently be extracted.

摘要： A message is embedded into a digital image by forming a digitized version of the message and convolving the digitized message with a random phase carrier to form a scrambled message. The scrambled message is then combined with the digital image to form an embedded message image that is near impossible to extract without knowledge of the formation of the random phase carrier.
