Design and Research of Off-line Checking System for Bank Notes
Ren De-jun · Microcomputer Information · 2009
A system based on machine vision for off-line checking the printing quality of bank note was proposed. The principle of the system, the segmentation algorithm of dot characters and recognisition method are introduced. Using Shape edge template matching technique to find the feature point and abstract the area of ROI automatically, calculate number of the pixels that the connected areas have to remove noise further. The system realize real-time detecting of banknotes. Experiments show the processing and recognisition speed is 15 papers per second, the instruction accuracy is 100%.
