An OCR system for business cards
H. Saiga, Y. Nakamura, Yoshinobu Kitamura, Tetsuo Morita · 2002
An experimental business card recognition system is described that recognizes Japanese business cards of a wide variety both in formats and fonts. It also classifies recognition results into several predefined categories so that a business card database is built automatically. The overall procedure divides into a character recognition phase and a linguistic processing phase. In the first phase, the system gives a strictly local approach toward line segmentation to cope with slanted images. In the linguistic processing phase, recognition result strings generated in the former phase are analysed, classified and verified with the help of built databases. Some experimental results are also discussed.>
