Abstract:
Disclosed are a magnetic ink character recognition method, apparatus and system. The method includes: reading a magnetic signal of a magnetic ink character on a medium to be recognized; acquiring the amplitude characteristic data of the magnetic ink character according to the magnetic signal thereof; and performing spectral angle cosine match processing on the amplitude characteristic data of the magnetic ink character to obtain the recognition result of the magnetic ink character. The present method can reduce the stability requirements on the magnetic signal and improve the recognition rate of the magnetic signal.
