Segmentation and recognition of unconstrained numerals on Chinese bank-check

The methods of segmentation and recognition of unconstrained numerals on Chinese bank check are discussed for building a recognition system. The combination-segmentation method of connected domain and projection is proposed to segment each digit. This segmentation method provides a way to solve the problem of segmentation of the connected digits with a connecting stroke. Three classifiers are designed independently with different methods using different features of handwritten digits. They can compensate each other when confusing digits are met. Under the limitation of fault-tolerant rate, and with the three classifiers of high isolated digit recognition rate, the check recognition rate of the system is practical in routine work of bank.
