    摘要: Disclosed is a computer implemented method of detecting a defect in a printed image, the method comprising the steps of: receiving a target image comprising digital image data representing a scan of the printed image; receiving a reference image comprising digital image data representing a reference of the printed image; calculating a structural dissimilarity measure, D, associated with a target pixel located in the target image and a reference pixel located in the reference image; and, determining on the basis of the structural dissimilarity measure whether a defect is present at the target pixel, wherein the structural dissimilarity measure is calculated using a structural measure, s, and a contrast measure, c; the structural measure calculated using a spatial cross-correlation associated with a target region, {right arrow over (x)}, containing the target pixel and a reference region, {right arrow over (y)}, containing the reference pixel, and the contrast measure calculated using a standard deviation associated with the target region, and a standard deviation associated with the reference region.

    摘要: A method and apparatus for encoding, in a simultaneous multiple security application, independently encrypted security data elements within a single matrix of blocks in a progressive barcode. The method and apparatus including, encoding information of a first data element within the matrix using black modules and, encoding information of a second data element within the matrix using color modules. The barcode being configured to be overprinted as it progresses through progressive states. The progressive barcode, resulting from the overprinting through the progressive states, masking the ability to conclusively determine the barcode in a previous state.

    摘要: A system (10) for generating an incrementally completed 2D security mark (20′″) includes a computer-readable medium encoded with a computer program. The computer program has computer readable code for selecting a symbology for the 2D security mark (20′″), computer readable code for selecting a scrambling technique for data to be placed into a carrier object (20, 20′, 20″, 20′″) of the 2D security mark (20′″) at each stage in the workflow, and computer readable code for selecting a manner in which a state change of the carrier object (20, 20′, 20″, 20′″) at each stage in the workflow results in a predictable change in the 2D security mark (20′″). The system the system further includes memory and a processor operatively coupled to the memory and to the computer-readable medium.

    摘要: A system for enhancing security printing includes a segmentation system, a secure database in operative communication with the segmentation system, a secure registry in selective operative communication with the segmentation system, and an analysis system in operative communication with the segmentation system and the secure database, and in selective operative communication with the secure registry. The segmentation system performs zoning analysis on a scanned image to identifying a list of regions in the image. The secure database stores at least one of i) a template, or ii) prior zoning output specification. The secure registry stores region of interest information and information pertaining to strategies for identifying a region of interest. The analysis system identifies the region of interest utilizing at least one of the secure database or the secure registry.
