| 20080273802 | Program and apparatus for forms processing - A form processing program which is capable of automatically extracting keywords. When the image of a scanned form is entered, a layout recognizer extracts a readout region of the form image, a character recognizer recognizes characters within the readout region. A form logical definition database stores form logical definitions defining strings as keywords according to logical structures which are common to forms of same type. A possible string extractor extracts as possible strings combinations of recognized characters each of which satisfies defined relationships of a string. A linking unit links the possible strings according to positional relationships, and determines a combination of possible strings as keywords. | 11-06-2008 |
| 20090041361 | Character recognition apparatus, character recognition method, and computer product - A character recognition apparatus includes a hash table registering unit and a recognition processing unit. The hash table registering unit creates a hash table indicating a characteristic of each of partial character images as an area of each character. The recognition processing unit divides an input image into partial input images, and calculates a characteristic of each partial input image. The recognition processing unit searches the hash table for a partial character image having a characteristic similar to that of each partial input image. The recognition processing unit compares a positional relationship of the partial input images with that of the partial character images to determine whether they match, and recognizes a character in each area of the input image. | 02-12-2009 |
| 20090110280 | IMAGE RECOGNITION APPARATUS, IMAGE RECOGNITION PROGRAM, AND IMAGE RECOGNITION METHOD - An image recognition method is conducted by recognizing logical elements based on a logical structure model set to correspond to the logical structure of an image of individual character strings, collecting information processed with the logical structure model of images of a logical structure, acquiring a recognition result when recognizing an image of a logical structure by processing information collected with a post-update logical structure model, | 04-30-2009 |
| 20090110282 | IMAGE RECOGNITION APPARATUS, IMAGE RECOGNITION METHOD, AND STORAGE MEDIUM RECORDING IMAGE RECOGNITION PROGRAM - An image recognition apparatus recognizes the correspondence between character strings and logical elements composing a logical structure in an image in which the character strings are described as the logical elements to recognize each logical element. The image recognition apparatus includes outputting means for outputting the recognized logical elements when the correspondence is recognized or re-recognized; first determining means for determining a certain logical element to be correct when input of a determination request to determine the logical element is received from a user; second determining means for determining the correctness of all the logical elements output before the logical element determined by the first determining means and is positioned according to confirmation by the user; and re-recognizing means for re-recognizing the correspondence between logical elements that have not been determined to be correct and the character strings on the basis of the determination content for each logical element. | 04-30-2009 |
| 20090125509 | DOCUMENT RECOGNIZING APPARATUS AND METHOD - A document recognizing apparatus includes a display control unit which displays a document data including a character string related to a character string selected by a user, and an area that includes at least a character string of the document data. | 05-14-2009 |
| 20090125797 | COMPUTER READABLE RECORDING MEDIUM ON WHICH FORM DATA EXTRACTING PROGRAM IS RECORDED, FORM DATA EXTRACTING APPARATUS, AND FORM DATA EXTRACTING METHOD - The form data extracting apparatus, even input form does not have a logical structure stored in the generic logical structure DB, by using logical elements in the existing logical structure and a registered form obtained on the basis of (a) the logical structure, (b) pieces of position information of the logical elements, and (c) a relation between the logical elements. A logical element and a logical structure are extracted from the input form, and the extracted logical structure can be defined as a new registered form or a new logical structure. | 05-14-2009 |
| 20090148049 | RECORDING MEDIUM FOR RECORDING LOGICAL STRUCTURE MODEL CREATION ASSISTANCE PROGRAM, LOGICAL STRUCTURE MODEL CREATION ASSISTANCE DEVICE AND LOGICAL STRUCTURE MODEL CREATION ASSISTANCE METHOD - A method for assisting in the creation of a logical structure model, which stores, from an image in which character strings associated respectively with a plurality of logical elements constituting a logical structure are described, the logical elements, character strings associated with the logical elements, and the logical structure, wherein character strings in an input image and the logical structure among the character strings in the input image are extracted, a logical element is selected among the plurality of logical elements according to the degrees of similarity between the extracted character strings and the character string associated respectively with the plurality of logical elements stored in the logical structure model, a character string associated with the selected logical element and a character string in the input image associated with the logical element based on the logical structure among the extracted character strings in the input image are extracted. | 06-11-2009 |
| 20090202152 | AREA EXTRACTION PROGRAM, CHARACTER RECOGNITION PROGRAM, AND CHARACTER RECOGNITION DEVICE - An area extraction method including obtaining a character lattice showing a connection relation between unit areas, which are obtained by separating a character string pattern in an image into patterns each recognized as corresponding to a single character, judging whether or not all combinations of each of the unit areas in the obtained character lattice and each of the unit areas in a regular lattice defining a regular connection relation between the unit areas are likely to be established, generating a path coupling between nodes corresponding to the combination of the unit areas which is determined as likely to be established, determining an optimum path from the generated paths based on a degree of coincidence with the regular lattice or the character lattice, and extracting from an image the unit areas in the character lattice corresponding to the determined optimum path. | 08-13-2009 |
| 20100005096 | Document type identifying method and document type identifying apparatus - A document type identifying apparatus includes in advance a database storing therein keywords used as keys that identify document types in association with each document type. The document type identifying apparatus aligns word strings written on a document and generates partial keyword strings for each keyword by using the keywords stored in the database. The partial keyword strings are to be checked for matching with the word strings written on the document. Then, the document type identifying apparatus checks matching of the grouped and aligned word strings with the partial keyword strings and obtains, for each keyword, each number of matched words with the highest matching rates between the grouped word strings that are successfully matched and the partial keyword strings. Then, each number of matched words is used to calculate each evaluation value to determine the document type. | 01-07-2010 |
