  • Patent number: 7558426
    Abstract: An output mechanism of a character recognition device includes a category classifier for classifying image data of characters to be recognized for each category recognized in character recognition processing, a clustering processor for determining feature values related to shapes of characters included in the image data in each category classified by the category classifier, and for classifying the image data into one or more clusters based on the feature values, and a screen creator for creating a confirmation screen for displaying the image data for each cluster classified by the clustering processor.
    Type: Grant

  • Patent number: 7006670
    Abstract: A technique which can generate stable virtual page marks even in a non-OCR form to stably identify the form. Key segments which can be stably detected within a form are predefined for the detection of virtual page marks, and the virtual page marks (circumscribed rectangle) are generated on the basis of the key segments. Redundancy is bestowed on the detection of the key segments, and substitute segments are defined so as to generate the virtual page marks on the basis of them even in a case where the key segment has failed to be detected due to a stain, a partial lack or the like.

  • Patent number: 6356655
    Abstract: An object is to enable designation of character frames and recognition of characters even where a document does not have any page mark or reference mark nor does a scanner have a function for detecting an edge of the document. Also, to enable identification processing of a bitmap image in an accerelated manner by comparing bitmap images on the basis of a circumscribed rectangle, which is formed solely from horizontal line segments that are recognizable at high-speed.
