    摘要： A reproduction apparatus (14) for reproducing documents (12) which comprise a base material. The apparatus comprises a platen (10) for forming a scanning area and for positioning the documents (12) on its one side, scanning means (18) for scanning the scanning area, and means for obtaining a relative movement between the scanning means and the documents in order to allow for the scanning. The scanning means (18) comprise a microwave system which is constituted by microwave transceivers (26) arranged in an array such that they can detect the presence of particles (13) which have electromagnetic properties which are substantially different from the electromagnetic properties of the base material and which are incorporated in at least a part of the documents (12), irrespective of the position of the documents (12) on the scanning area.

    摘要： An image recognition method and device detects an object mark reliably even when the mark is defaced with a different color. RGB signals are transmitted to color extraction unit (10). The color extraction (10) unit has a characteristic color extraction block (17) to extract the characteristic color of the object mark. A binary image is generated from the extracted pixels which are the color of the mark and stored in storage device (11). A mark detection unit (12) detects the location of the mark in the stored image data and an image extraction unit (13) extracts the region where the mark is located and obtains a feature count. A matching unit (14) compares the feature count with a reference pattern and finds the goodness of fit. A control unit (16) subjects the goodness of fit value to threshold value processing to determine whether this is a non-reproducible document. If the mark has been defaced with black ink, the pixels constituting the mark are extracted by a likely color extraction block (18). A binary image is generated and stored in storage device (11). Thus, the defaced mark can undergo the same recognition processing as the normal mark, and both can be recognized.

    摘要： An image character recognition process comprising: forming an image in a predetermined size and predetermined shape on a receiver member with a marking composition containing a superparamagnetic component; detecting the predetermined size and predetermined shape of the formed image by placing the resulting image bearing receiver member in a magnetic sensing field comprising at least one magnetic sensor and forming a magnetic size and magnetic shape profile map of the detected image; and recognizing the detected image by comparing the magnetic size and magnetic shape profile map of the formed image with reference magnetic profile image maps.

    摘要： Es handelt sich um ein Verfahren zum Erkennen von Druckbildern auf Dokumenten, Wertpapieren oder dergleichen, bei welchem die Druckbilder der zu prüfenden Dokumente in ihrer Gesamtheit oder in Teilbereichen elektronisch abgetastet, mit Referenzwerten verglichen und bei Vorliegen vorgegebener Kriterien spezifische Maßnahmen eingeleitet werden. Die den abgetasteten Druckbildern zugeordneten Daten werden vollständig oder teilweise zwischengespeichert und mittels vorgegebener Vergleichsprogramme auf das Vorhandensein von definierten Gesetzmäßigkeiten überprüft. Die spezifischen Maßnahmen werden dann abhängig vom Vorliegen dieser Gesetzmäßigkeiten eingeleitet.
