Embodiment Construction
[0029] The invention uses computer vision detection as an important technical means, comprehensively uses the knowledge of image processing and pattern recognition, and realizes the automatic recognition technology of banknote number images. Combined with the DSP circuit, through the acquisition of banknote number images, preprocessing, image segmentation, number body positioning, number body recognition and other algorithms, a DSP-based banknote number recognition and recording system has been completed in terms of software and hardware .
[0030] The method for automatically identifying banknote numbers can be implemented according to the following steps:
[0031] 1) Image preprocessing;
[0032] 2) Character positioning;
[0033] 3) feature extraction;
[0034] 4) Character recognition.
[0035] Wherein, step 1) may include performing noise reduction and segmentation processing on the collected original reading image, using template filtering method to remove noise in t...
