Abstract: A method for enhancing security printing of a layout template is disclosed. The method includes receiving the layout template, and acknowledging one or more constraints for the layout template. At least one unconstrained layout element of the layout template is varied, thereby generating a varied layout template. The varied layout template is printed and scanned. The method further includes determining a number of bits that can be encoded in the varied layout template, where the number of bits depends on the varying of the at least one unconstrained layout element.

Abstract: A void pantograph and a method for generating the same are disclosed herein. The void pantograph includes a foreground portion based on a region of an image that is defined using a predetermined filter, and a background portion based on another region of the image that is defined using the predetermined filter.

Abstract: Methods for selecting metrics for substrate classification, and apparatus to perform such methods. The methods include determining a value of a metric from an image of a substrate sample for each substrate sample of a plurality of substrate samples, wherein the metric is indicative of a surface texture of each substrate sample and iteratively assigning substrate samples of the plurality of substrate samples to an aggregate of a particular number of aggregates in response to a value of the metric for each substrate sample until a convergence of clustering is deemed achieved, then determining an indication of cluster tightness of the particular number of aggregates. The methods further include selecting or ignoring the metric for substrate classification in response to the indication of cluster tightness of the particular number of aggregates.

Abstract: A printed information device includes a region of interest in an image, and at least two channels assigned to the region of interest by different means of logical partitioning. The region of interest represents a physical area of the image. Each of the channels has a different error tolerance. Continuous and/or cyclic information is independently encoded in each of the at least two channels. The deterrent is configured to be read substantially simultaneously by at least two distinct reading strategies.

Abstract: A method for testing image pipelines includes transforming an untransformed captured image multiple times using a plurality of pipelines, thereby generating a plurality of transformed images, and comparing a functional set of metrics associated with each of the plurality of transformed images with a functional set of metrics associated with each image in a ground truth set. From the comparison, a determination is made as to which of the plurality of pipelines generates a transformed image that is functionally closest to an image in the ground truth set.

Abstract: A counterfeit detection system is disclosed herein. The system includes an image reduction system for minimizing size of at least one original image using a plurality of different reduction strategies to generate a plurality of minimized images. The system further includes a classification system which includes a first sub-system for generating at least one accuracy comparative assessment metric for each of the plurality of minimized images, a second sub-system for comparing the at least one accuracy comparative assessment metric for each of the plurality of minimized images with an accuracy assessment metric for the at least one original image, and a third sub-system for determining if at least one of the plurality of minimized images can be transmitted with improved or equivalent classification accuracy at a reduced bandwidth when compared to the original image are also part of the system.

Abstract: A method for using void pantographs involves generating a test sheet including multiple void pantographs, where each of the multiple void pantographs includes a pantograph foreground and a pantograph background. The test sheet is printed, and from the printed test sheet, at least one of the multiple void pantographs having a covert or semi-covert pantograph foreground and background is identified. The printed test sheet is scanned, and from the scanned test sheet, at least one of the multiple void pantographs having an overt pantograph foreground is identified. A workflow is developed for the at least one of the multiple void pantographs having both i) the covert or semi-covert pantograph foreground and background after printing, and ii) the overt pantograph foreground after scanning.

Abstract: 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.
