Abstract

The automatic sorting of bank bill has become very important to speed up the office automation. Some methods have been reported to classify the denomination and directions of bank bill. But there were no reports about defile detection. In this paper, we designed a fast and effective algorithm to detect defiles on bank bill. We make use of mathematical morphology image processing to do shift and rotation correction. In order to reduce CPU time, we adopt pyramidal strategy to do template matching. In addition to these, we designed a check-up means to eliminate dummy defiles. The test results prove that this algorithm is robust. It's not sensitive to random noise and geometry distortion. In a word, this algorithm is quite effective.
