摘要:
Die aus den einzelnen Kenngrößen einer abzubildenden Struktur in einer Interferenzebene (IFE) gebildeten analogen Summenkenngrößen werden in geringer Anzahl unmittelbar als elektrische Signal verarbeitet, bewertet und digitalisiert der weiteren parallelen Verarbeitung zugeführt, so daß trotz der Anwendung des Holografieprinzips komplizierte optische Systeme und Filtersteuerungen vermieden werden. Filterungen zur Erkennung von bereits bekannten Strukturen können vielmehr rein digital durch Vergleich der erhaltenen Abbildungsinformationen mit den einzelnen Strukturen zugeordneten Bezugsinformationen (BZl..) digital vorgenommen werden. Die Abbildung von Strukturen in der Interferenzebene (IFE) kann direkt mit kohärenter Strahlung durch holografische Abbildung oder aber indirekt durch Modulation von kohärenten Trägerwellen in getrennten Kanälen mit den Strukturkenngrößen erfolgen, wobei für die Interferenzbildung vorzugsweise ein optisches System, z.B. in Form eines Sternkopplers mit zwei an diesen angeschlossenen kohärenten Glasfaserbündeln, verwendet wird.

A self-organizing pattern learning system comprises an optical pattern correlation degree detecting means, which comprises a pattern storing means for storing a plurality of patterns, an input pattern displaying means for displaying a presented input pattern, and a photo detecting means. All or two of the input pattern displaying means, the pattern storing means, and the photo detecting means are located at positions adjacent to each other. The photo detecting means optically detects a degree of pattern correlation between the input pattern displayed on the input pattern displaying means and each of memory patterns stored in the pattern storing means. A learning pattern creating means creates a group of learning patterns in accordance with the degrees of pattern correlation, which have been detected by the optical pattern correlation degree detecting means, and the input pattern. A memory pattern updating means updates the memory patterns, which are stored in the pattern storing means, in accordance with the learning patterns, which have been created by the learning pattern creating means.

Apparatus for comparing an input genome sequence with one or more reference sequences comprises signal generators (10) for generating an input signal for each occurrence of each base component type (A,C,G,T) of the input sequence. A respective optical correlator (23-26) is provided for each base component type. Each correlator detects a match or near match between the occurrences of the respective base component type in the input sequence and the occurrences of that component type in any of the reference sequences, and produces a respective correlation signal. Decision-making circuitry (31) responds to the correlation signals from all of the correlators to provide an indication of a match or near match between the whole input sequence and any of the reference sequences.

A method and apparatus for dynamically switching between fonts or groups of fonts in an automatic character recognition system (10). The feature vector that the recognition system produces for each character on a document is normalized to unit length (24) and projected onto a set of eigenvectors (28). A memory (26) in the character recognition system stores several sets of eigenvectors, each set corresponding to a particular character font. A switch character which is included between a first and second group of characters triggers the selection of the appropriate set of eigenvectors for the succeeding font.

In accordance with an embodiment of the invention, a method for embedding key information into a printed document is disclosed. The method comprises creating a first section comprising a first ink having a first color under white light; and creating a second section comprising a second different ink. The second ink comprises a fluorescent ink and has a second color under white light which is substantially the same as the first color, and the fluorescent ink has a fluorescence when subjected to fluorescent-exciting radiation. The first section and the second section are visually indiscernible from each other on the printed document in white light. Also, the second section comprises key information, which is selected or highlighted by a user during creation of the document, and the first section comprises non-selected information.
