  • Patent number: 7877238
    Abstract: A data classification supporting method capable of easily discriminating a cell to which unknown data belongs and cells similar to the unknown data from each other is obtained. This classification compares cell vector data of each cell with the unknown data, decides a cell having cell vector data closest to the unknown data and cells having cell vector data secondly to nthly close to the unknown data as a minimum cell and similar cells respectively and displays a minimum cell mark and similar cell marks indicating the minimum cell and the similar cells respectively on a classification map.

  • Publication number: 20050058330
    Abstract: A method of displaying a smear image capable of reducing a time required for displaying the smear image on a user terminal is provided. This method of displaying a smear image comprises steps of acquiring a prescribed partial image necessary for display, included in a plurality of partial images obtained by dividing the smear image and stored in a first database of an image server, from the image server through a communication network and displaying the prescribed partial image and acquiring another partial image required for display due to display scrolling on the terminal from the image server through the communication network and displaying the partial image in response to the display scrolling.
