摘要： A method and apparatus for generating a degraded dictionary automatically is presented in this invention. Herein, a degraded pattern generating means generates a plurality of degraded patterns from an original character image, based on a plurality of degradation parameters. A degraded dictionary generating means generates a plurality of degraded dictionaries corresponding to the plurality of degradation parameters, based on the plurality of degradation patterns. Finally, a dictionary matching means selects one of the plurality of dictionaries which matches the degradation level of a test sample set best, as the final degraded dictionary. In this invention, various degraded patterns can be generated by means of simple scaling and blurring process for establishing degraded dictionaries. Therefore, the invention can be implemented simply and easily. The method and apparatus of the invention can not only be used in character recognition field, but also can be used in other fields such as speech recognition and face recognition.

摘要： A ruled line extracting apparatus obtains circumscribed rectangles of pixel concatenation regions included in an input pattern, and calculates the most frequent value of their heights. Additionally, the apparatus integrates segments by ignoring a wild card segment, and calculates the most frequent value of height/width of extracted straight lines and segments structuring the straight line. Next, it performs a process for integrating/deleting straight lines using each threshold value based on the highest frequency value. Then, it checks/deletes a straight line according to a distribution of black pixels around the straight line, and recognizes the remaining straight lines as ruled line candidates.

摘要： An optical module has a plurality of filters that transmit or reflect lightwaves. First optical paths that guide a lightwave, second optical paths that guide only a lightwave having a specific wavelength, which passes through or is reflected by the filter, from the filter, third optical paths that guide a lightwave having a specific wavelength to the filter, and fourth optical paths that guide a lightwave from the filter are connected to the filters. The first to fourth optical paths are supported by optical path supporting members. A first optical fiber is connected to any one of the first optical paths. Second to fourth optical fibers are connected to the second to fourth optical paths, respectively, corresponding to the filter corresponding to the first optical path to which the first optical fiber is connected. Ends of the first to fourth optical fibers are supported by fiber supporting members. Each of the optical path supporting members is provided with a fitting portion to which the fiber supporting member is detachably attached.
