    摘要: The disclosure describes systems for creating and authenticating printed objects using authentication and copy detection watermarks. For example, one verification system includes a watermark decoder and a verification module. The watermark decoder detects a copy detection watermark in a printed object to determine whether the printed object has been reproduced. The verification module processes a message decoded from an authentication watermark on the printed object to authenticate the printed object or bearer of the printed object. The authentication and copy detection watermarks may be implemented as the same or different watermarks. For example, the copy detection watermark may be a fragile watermark that carries the message and that degrades in response to a reproduction operation, such as photocopying or scanning and then reprinting the object. Alternatively, the authentication and copy detection watermarks may be separate watermarks embedded in an image that is printed on the object. The authentication watermark, in some applications, includes an identifier that links the object to a database entry with related information about the object. This related information can be used to check the bearer of the object by comparing it with attributes of the bearer (such as a user ID or photo) or the validity of the object by comparing it with attributes that are visible or machine readable on the object.

    摘要: A three-dimension distance time-of-flight system is disclosed in which distance values are acquired by a plurality of sensors independently from each other. For use with this and similar systems, Z-distance accuracy and resolution are enhanced using various techniques including over-sampling acquired sensor data and forming running averages, or forming moving averages. Acquired data may be rejected if it fails to meet criteria associated with distance, luminosity, velocity, or estimated shape information reported by neighboring sensors. A sub-target having at least one pre-calibrated reflectance zone is used to improve system measurement accuracy. Elliptical error is corrected for using a disclosed method, and reversible mapping of Z-values into RGB is provided.

    摘要: A cigarette inspection device includes four sensors, two for sensing the ends and one for sensing the middle portion of a cigarette to detect loose tobacco and filter presence at the ends, and the presence of a foil band at the middle portion. The fourth sensor provides machine timing information to determine the three conditions of detection. Binary information is then input to a PLC for data reduction and rejection, if the conditions are not present. The program in the PLC allows the end of the cigarette to be scanned multiple times for loose tobacco. Also, foil sensing and filter sensing are done along with the loose tobacco sensing. A shift register is loaded with the resultant detection data, and a reject valve or similar device is operated to remove faulty cigarettes from the product stream.

    摘要: The present invention disclosed a method and system inspecting cotton web homogeneity by a digital image processing technique, in particular, for an on-line cotton web homogeneity test. It uses optical principles in conjunction with a charge coupled device type camera to find a theoretical equation indicating the correlation between the transmittance of cotton webs and basic weights (weights per unit area). Next, the invention makes use of a numerical analysis method to find the optimal approximation equation representing a relationship between measured transmittance and basic weights of cotton webs. When executing an on-line inspection, a system according to the invention detects the transmittance of cotton webs by means of the computer controlled visual device and then calculates correlated data of cotton web homogeneity variations according to the approximation equation acquired previously. Besides, the system can monitor production operation and detect any abnormal conditions or periodical variations in production through a quick Fourier transformation of homogeneity variations. The invention can be applied to on-line web homogeneity tests either for cotton webs or for other materials like paper or non-woven fabric.

    摘要: OLE-like principles are implemented using watermark data in digital objects in order to effect object linking or embedding. In one embodiment, a photocopier scans an original paper document to produce image data. This image data is analyzed for the presence of watermark data identifying a graphic on the document. With this watermark identifier, the photocopier can query a remote image database for pristine image data corresponding to the scanned graphic. This pristine data can be relayed from the remote database to the photocopier and substituted into the scanned image data. Output printed from the photocopier is thus based, at least in part, on pristine image data, rather than on image data that has been subjected to various corruption mechanisms (e.g., degradation of the original paper document, artifacts due to scanning, etc.). A “photocopy” better than the “original” can thereby be achieved.

    摘要: Apparatus and an accompanying method, for generating a cryptographic identifier for a non-marked image and embedding that identifier within the image itself in order to generate a “watermarked” image; for subsequently detecting that watermark in a test image; and the watermarked image so formed. First, pixel values for a non-marked image are transformed, either directly or after being enhanced, into a series of transform coefficients. A set of pseudo-random perturbation values which collectively constitute the watermark is determined wherein each of these values is heuristically selected, such that all these values collectively satisfy a plurality of different mathematical constraints and each such value preferably equals a relatively small value in a predefined range. These perturbation values are then added to the transform coefficients. Resulting perturbed coefficients are then inversely transformed back to pixel values to form the watermarked image. To detect whether a test image contains the watermark and hence is a copy of the watermarked image, the pixel values for the test image are transformed to yield transform coefficients. A plurality of different mathematical tests or a majority type rule is then used, in conjunction with the perturbation values, previously used to create the watermark, and these transform coefficients to determine whether the perturbation values collectively exist in the test image, and hence whether the watermark is present or not.
