ExperVision OCR has customized OCR software and solution that can meet the requirements of Euro Banknote and Serial Number Recognition.
Our Solution for Euro Banknote & Serial Number recognition is as below
1) Pre-processing for Euro Banknote & Serial Number Recognition
The basic pre-processing includes binarization, trim, fattens and etc. As the backgrounds of each Banknote value are different and quite fixed, and based on our observation and analysis, we configured 7 pre-processing modules, which can be called based on the inputting Banknote value. By so doing, the efficiency and stability have been greatly increased.
2) OCR SDK fine tuning for for Euro Banknote & Serial Number Recognition
ExperVision OCR need to modify core algorithms and process flow to recognize special images like images of misalignment chars. And special training for OCR-B font also needs to be added. For example, the vertical line of number 4 is very short after binarization, so special training needs to be added for recognizing such number.
3) Post-preprocessing for Euro Banknote & Serial Number Recognition
- Post-processing rules: every Serial Number has 12 Chars and first char is letter, the rest ones are numbers.
- Output Format Customization: outputting text format, saving in input folder and etc based on Specifications.
- Output required info containing Serial Number recognition result and confidence level of each char.
