IPC: G06K9/70
Filed: 1989-07-07
Abstract: PURPOSE:To perform character recognition with high likelihood by performing comparative collation with a second dictionary consisting of a reference pattern for a character with low frequency in use sequentially when the collation result of a character pattern is less than a prescribed level. CONSTITUTION:The character is classified at every frequency in use at a dictionary part 4, and is stored as individual dictionaries (1)-(3), respectively. Also, a character pattern collation part 3 is connected to a reject level judging part 5 which employs the collation result with a dictionary with high frequency in use when it exceeds the prescribed level, and performs collative comparison with the dictionary with low frequency in use when it is less than the prescribed level. Therefore, it is possible to prevent the character seldom used outputted accidentally as the recognition result, and to improve the accuracy of the recognition result, and furthermore, since collation is separated corresponding to the frequency in use, the collation of an ordinary character with the character with low frequency in use can be omitted. In such a way, the character recognition with high likelihood can be performed.
