Post-processing device of character recognition

As this is a public information case, the full text was not included.

FIG. 3 is a block diagram showing the device configuration of an embodiment of the present invention, FIG. 4 is a flowchart of character recognition processing in the embodiment, and FIG. 8 is a block diagram of a circuit for executing word combination.

Claims (5)

Means for inputting a digital image, means for recognizing a character pattern existing in the digital image to obtain one or several candidate characters for each character pattern, a word dictionary for storing several words, the one or Means for combining a candidate character string obtained by combining a plurality of candidate characters with a word included in the word dictionary, and means for selecting one from several kinds of word combination enhancements, wherein the word is selected by the selected word combination aspect. A post-processing apparatus for character recognition which changes a combination method or parameters in a combining means. The word recognition means according to claim 1, wherein said word combining means has a means for adding candidate characters to candidate letters of a recognition result according to a predetermined rule, and the rules of the collection are different for each aspect of word combination. Aftertreatment device. The method of claim 1, further comprising a plurality of word dictionaries, a relationship dictionary that stores the mutual relations of words included in the plurality of word dictionaries, and means for obtaining candidate words for each of the plurality of character pattern groups. By recognizing a plurality of character pattern groups present in the input digital image, candidate characters for each character pattern included in each character pattern group are obtained, and a candidate word is obtained by executing word combination for each character pattern group. A post-processing device for character recognition which selects candidate words whose information contained in a relation dictionary matches a connection relationship between candidate words. The method of claim 1, wherein one of the aspects of word combining is character recognition for controlling word combination to be executed again by changing a method or parameter of word combining when no candidate word obtained as a result of word manipulation exists. Aftertreatment device. The post-processing device for character recognition according to claim 3, wherein the candidate word obtained as a result of the word combination does not contain the candidate candidate word and then the candidate word is selected by the connection relationship between the candidate words. . ※ Note: The disclosure is based on the initial application.
