  • Patent number: 11151373
    Abstract: An information processing apparatus includes processing circuitry. The circuitry acquires first ledger sheet definition information and second ledger sheet definition information from a memory. The first ledger sheet definition information defines relative positions of an item and a value of the item in a ledger sheet. The second ledger sheet definition information defines relative positions of an item and a value of the item in a ledger sheet unique to a user. Based on at least one of the first ledger sheet definition information and the second ledger sheet definition information, the circuitry extracts an item and a value of the item from reading result information that associates a character string read from a ledger sheet image with information representing a position of the character string, and the circuitry outputs the extracted item and value of the item as a recognition result.

  • Patent number: 8693790
    Abstract: Disclosed are a form template definition method and a form template definition apparatus. The form template definition method comprises a cell extraction step of analyzing an image of a form so as to extract one or more cells from the image of the form; a cell classification step of classifying the extracted cells; and a cell attribute definition step of defining attributes of the extracted cells class by class. If an attribute of a first cell in one class is defined, then other cells in the class automatically copy the attribute of the first cell. As a result, the work amount of form template definition may be dramatically reduced by employing the form template definition method and form template definition apparatus.

  • Patent number: 7873239
    Abstract: A first direction determining unit determines, with respect to each of directions in image data corresponding to an image that contains text, a degree of certainty that the direction corresponds to a predetermined direction of the image to obtain a first direction with the highest degree of certainty and a second direction with the second-highest degree of certainty. When the first direction is opposite to the second direction, a second direction determining unit determines whether the predetermined direction corresponds to the first direction or the second direction based on a position of a text line extracted from the image data.
