| The People's Bank of China based on overseas advanced experience, decided the construction of the national check image exchange system supported by the image technology, stopped the exchange of the check, changed the check reckoning mode, realized check used in nationwide. This system's key question lies into the check image verification, including to in image face value essential factor valid verification as well as copy of a seal used for verification purposes checkup, but present general artificial verification paper nature check method already completely unsuitable system request. Therefore exploring a set of appropriate verifications methods is a topic which the researcher faces.OCR is carries on the scanning recognition using optics technology to the writing and the character, transforms technology which the computer encodes. This technology at present quite is mature, has widely applied to domain and so on bar code examination, hand-written input, also has the broad application prospect in the bank bill processing aspect.This article starts with the Pattern Recognition, the Image Recognition and the OCR technology basic principle, studies the verification method of the check image face factors validity, selects the appropriate method and the algorithm, finally completes the design of the check image exchange system. |
