Abstract:

Based on pattern transform method with cosine function, a new pattern generation method for handwritten Chinese characters was proposed, which improved the performance of recognition system for handwritten Chinese characters. By using transform method with cosine function, the number of learning patterns was increased. Patterns generated artificially in this way were selected using pattern selection method and the patterns unsuitable for learning were discarded. The recognition experiment on HCL2000, a handwritten Chinese character database, showed that our method improved the recognition precision of whole system.

Key words: pattern recognition, pattern generation, Chinese character recognition, pattern transform with cosine function
