End-to-End Bank Card Number Recognition Algorithm Based on DenseNet

Printed bank cards number, which are usually black and not easily confused with the background, is easy to split and recognize; embossed bank card, the color of bumped card number is similar to background, characters difficult to split and identify. This paper proposes an end-to-end bank card number recognition algorithm, first uses CTPN network for text detection, then sends the test results into the DenseNet network to identify, finally the card number is output according to the text length. Experimental results show that the algorithm can achieve the automatic identification of the two types of bank card, with high recognition rate and accuracy.
