Method and apparatus for identifying MICR characters

摘要

A method and apparatus for reading MICR characters is disclosed, in which both magnetic and optical data may be read and stored. Each type of data is analyzed to identify possible character values. In one disclosed analysis method, the data is first evaluated in a coarse analysis then analyzed using a fine analysis which may lead to the identification of characters. The analysis of characters may involve generating frequency spectrum data from scanned data and assigning character values based on the frequency spectrum data.
