Second-generation ID Number Recognition System Based on Digital Devices

Abstract

Abstract:

This paper studies second-generation ID number recognition technology based on digital devices. For the preprocessing, a method based on Sobel operator template

is provided to judge ID image vertical shooting or down shooting. For the characters segmentation, an improved vertical projection method based on the Shenjun binary edge image

is provided, which solves the segmentation of adhesion character effectively. For the characters recognition, the method of the blur grid eight-direction gradient feature

combined with K-nearest neighbor classifier is used for classification. After many experiments, the results show that this system can accurately locate and recognize ID number

for its high recognition accuracy and it is of general versatility.

Key words: second-generation ID number recognition, preprocessing, edge detection, Hough transform, segmentation, recognition
