A method for identifying payment forms accurately identifies types of forms without adding special form identification data. A payment form discrimination method for discriminating payment forms which state a payee account number and a payment amount includes a step of acquiring an image of the form, a step of making a search for the payee account number in the image in accordance with an account number searching rule, and a step of discriminating the type of form based on the searched payee account number. Types of forms can be identified accurately and fast without adding special form identification data, because the form identification is performed using easily searchable account numbers.

Payment form discrimination method and apparatus

Collation can be carried out at a high speed without reducing the accuracy thereof, whereby processing of identifying documents is accurately performed at a high speed. To this end, characteristic data of a predetermined pattern is registered in advance. Characteristic data in a first area greater than an area of the predetermined pattern registered in advance in an image to be identified is compared and collated with characteristic data of the predetermined pattern. A second area smaller than the first area is cut out from the first area based on the result of comparison, so that characteristic data of an image in the second area is compared and collated with the characteristic data of the predetermined pattern, thus making it possible to identify the predetermined pattern contained in the image based on the result of comparison.

A data sheet identification device of the invention includes: a character/graphics extracting section, an identical shape deciding section, a graphics collating section, an identification code/data sheet ID identifying section for collating characters that have been decided to have the same shape with an identification code/data sheet ID database in which a plurality of characters showing features of a plurality of data sheets respectively have been registered, and an identifying section for uniquely identifying the data sheet based on a result of the collation by the graphics collating section and a result of the collation by the identification code/data sheet ID identifying section.

Data sheet identification device

An image collating apparatus and an image collating method, in which a document larger than an image reader can be collated using a preregistered image even in the case where the document is read by the image reader, are disclosed. The image of the document read by the image reader is collated sequentially with the document images of different sizes preregistered in a data base. The document size is determined from the document image input from the image reader. In the case where the document size is smaller than the preregistered image size, the preregistered image is retrieved in accordance with the document size, so that the document features are extracted and matched between the read document image and the registered image set in size to each other, thereby collating the read image with the preregistered image.

Disclosed is a format recognition method, apparatus and its storage medium for automatically recognizing the format of a form, whereby the format is automatically determined by examining the arrangement of the smallest rectangles. According to the present invention, the smallest rectangles are extracted from a form, and the positional relationship of these rectangles is obtained. The attribute of the smallest rectangle is determined from the positional relationship. In accordance with the attribute, the smallest rectangles are sorted into a headline portion and a data portion, and a character string in the data portion is recognized.

In order to quickly and economically evaluate cleanliness of a metal with high representativity when quantities, compositions, etc., of non-metallic inclusion particles existing in a metal and resulting in product defects are evaluated by a sample collected during the production process of the metal, the present invention provides an evaluation method involving the steps of levitation-melting a metal piece for a predetermined time by cold crucible levitation-melting means, discharging non-metallic inclusion particles contained in the metal piece to the surface of a molten metal, and directly analyzing a curved and non-smooth sample surface after solidification by a fluorescent X-ray analysis method using an energy dispersion type spectroscope, or by other chemical or physical measurements, to measure or analyze the quantities of elements constituting the non-metallic inclusion particles and to determine quantity of the non-metallic inclusions.

Evaluation apparatus for cleanliness of metal and method thereof

Disclosed are a method of and an apparatus for extracting a dotted line from an binary image of a document, and a storage medium thereof. The isolated points are extracted from the binary image. The isolated points configuring a candidate of the dotted line are extracted based on a positional relationship between the extracted isolated points. A validity of the isolated points configuring the candidate of the dotted line is checked. The dotted line from a positional relationship between groups of the extracted isolated points of the candidate of the dotted line. The dotted line can be thereby precisely extracted even if some isolated points are lost due to an. under-density of the image etc.

Method of and apparatus for extracting dotted line, and storage medium thereof

Characters of data on a document are recognized by automatically determining the definitions of characters of the data from the arrangement of character strings of the data. Character strings on the document are extracted by reading the document, and headers and data on the document are distinguished from each other by determining the positional relationship between the character strings. Character attributes of the data are determined by recognizing characters of the character strings of the headers using a header recognition dictionary. Characters of the character strings of the data are recognized according to the determined character attributes of the data. Since character attributes of the data are determined from recognized characters of the headers after the headers and the data are distinguished from each other from the layout on the document, it is possible to enter automatically the character attributes of the data.

Method of recognizing characters

This invention relates to a process for enriching carbon 13 by mixing a halogenomethane containing one or more fluorine atoms and carbon 13 of natural isotopic abundance with one or two or more additive gases selected from a group of oxygen-containing oxidizing agents, halogens, and hydrogen halides, irradiating the resulting raw material gas mixture by a carbon dioxide laser to cause selective dissociation and reaction of the halogenomethane of carbon 13, separating the unchanged substances from the reaction mixture to obtain a product enriched with carbon 13, further converting the enriched product to carbon monoxide, and enriching carbon 13 by low-temperature distillation of the carbon monoxide. The process has advantages of low overall energy consumption, high yields of carbon 13, easy separability of the unchanged substances and high degrees of carbon 13 enrichment.
