A fault tolerant Chinese bank check recognition system

In this paper, a practical fault-tolerant Chinese bank check recognition system is presented and analyzed in detail. The first part discusses some preprocessing technologies including software-location of the scanned check skew correction of each sub-image containing various numeral strings and segmentation of these strings. Then, a high performance SOM classifier is adopted as the classifier to the segmented numerals. After that, a new idea of fault-tolerant recognition is proposed and the post-processing method is introduced. This system reaches high accuracy and high reliability simultaneously
