Abstract
A character recognition method and apparatus which assembles similar character patterns into groups. By performing character recognition for each character of the group and comparing the recognition results for the group, a single recognition result can be obtained for the entire group which is quite accurate. Alternatively, a representative pattern may be generated for the group and a single recognition processing performed on this pattern in order to reduce the amount of time necessary to perform the character recognition process. When the result of the character recognition does not strongly indicate a single recognition result, the probability of appearance of individual characters and/or groups of characters such as digrams or trigrams can be analyzed to obtain more accurate results.
