The serial numbers of RMB is unique that is the sign of difference between other notes.Used the methods of based on a projection method to locate numbers' area,and proposed a method that is adopted the shortest path of two-way searching best concave-convex position of the adhesive characters outline to segment the single characters.Conducted line projection and column projection to the serial number of binary to locating the area of the note numbers for rough and fine positioning two steps.In order to improve the accuracy of the adhesive characters' segment,adopting the shortest path of two-way search best concave-convex position to Segment the single characters.The experimental results show that the projection method can position notes of serial numbe rapidly and accurately.The shortest path of two-way search best concave-convex position to Segment the single characters than better the one-way path.And then it was removed the adhesive noise that can segment the serial number character of notes rightly and effectively.
