A crown word on a Chinese RMB note is a sequence of characters that uniquely identify a bank note. Training set sampling is very important in the recognition system of RMB crown word, which directly affects the accuracy of the recognition system. Image preprocessing operations require a number of properties on the crown characters such as the location, tilt correction, attitude, adjustment, noise reduction, binarization and single character segmentation and so on.
