  • Case-based system and method for generating a custom document
    Publication number: 20040019847
    Abstract: What is disclosed is a case-based method which specifies previously created documents as cases in a case base, and provides a generalized method for using these previous documents to create a new desired document. The new problem (i.e., the document you are trying to create) is expressed, using any/all case features (e.g., new problem constraints, creator intent, document-genre, etc.). A matching process is performed in order to retrieve documents similar to the desired document from the case base. A selection process chooses one or several of the best matching cases as starting points for creating the new document. The retrieved document(s) are then adapted to create the new desired document. This new document is optionally stored back into the case base as a new case.

  • Constraint-optimization system and method for document component layout generation
    Publication number: 20040019850
    Abstract: What is disclosed is a system and method for specifying a custom document as a multi-criteria constraint optimization problem, and a method to automatically create the specified document using existing constraint optimization solving algorithms. The present method specifies the document, its content components, its layout requirements, and its desired aesthetic criteria are expressed as elements of a constraint optimization problem which when solved, results in an automated document layout for the set of content components that satisfies not only certain primitive content and layout constraints, but which also advantageously fulfills desired design properties and which provides a way to ensure that the generated document is well designed.

  • Optical transmission apparatus
    Publication number: 20040017966
    Abstract: Master node #0 and a plurality of slave nodes #1 to #4 are connected to one another via a plurality of optical couplers 20. Each of the nodes is controlled so that signal transmission between the nodes by a bus connection and a link connection is conducted via the optical couplers. In the link connection, the master node transmits bit signals corresponding to the number of the slave nodes. Each of the slave nodes transmits a bit signal with allocating the signal to a predetermined bit.

  • Electronic filing system with file-placeholders
    Publication number: 20040019613
    Abstract: In an electronic document filing system, placeholder objects are used to provide an explicit representation of document files which are not yet present but which are explicitly expected by the system. A placeholder object can be a real filing system object, which may be processed by the filing system in the same manner as any other filing system object, and can include filing system data such as file metadata. The metadata may be associated with an expected source for the document file in, for example, filing systems, messaging systems, workflow systems, and document scanning systems.

  • System and method for constraint-based document generation
    Publication number: 20040019852
    Abstract: What is disclosed is a system and method for specifying a custom document as a constraint satisfaction problem (CSP) to create the specified document using existing constraint solving algorithms wherein the document, its content components, and its layout requirements as elements of a constraint satisfaction problem which when solved, results in an automated document layout for the set of content components. This enables an easier (i.e., automated) custom document creation process while providing a wider array of output documents.

  • Image processing apparatus and print control method therefor
    Publication number: 20040017576
    Abstract: An image processing apparatus for processing image data comprises a printer for printing processed image data on recording paper; an image data receiver for receiving image data transmitted thereto via a network; storage unit for storing the image data received by the image receiver; a print controller for controlling printing of the image data stored in the storage unit on the recording paper; and one or more feed trays that load recording paper loaded therein and feed the loaded recording paper to the printer, wherein, if recording paper of the image data is larger in size than any recording paper loaded in the feed trays, the print controller reduces in size image data to fit with largest-size recording paper of the recording paper loaded in the feed trays, and prints the size-reduced image data on the largest-size paper.

  • HVQ-based filtering method
    Patent number: 6683994
    Abstract: A method for filtering digital data using techniques normally utilized for data compression prior to transmission or storage. These techniques include codebooks and codewords as found with vector quantization and the approach of using look-up tables as found in hierarchical vector quantization. The method described herein achieves exemplary filtering results by using the above techniques in an overlapping fashion rather than being directed in the usual manner so as to achieve data compression. The codewords thus generated by this series of overlapping look-up stages are approximations of the input data neighborhoods. The method achieves filtering by the processing and applying of a mapping function to these output codewords, thereby associating filter output values to the input digital data.
