Abstract

Abstract:

In order to solve the problems existing in the application of traditional two-dimension barcode to mobileterminals,a recognition system of Tcode coding and decoding based on embedded system,which consists of encoding,decoding and recognition modules,is developed to simplify the two-dimension barcode.In the investigation,novel coding and mapping schemes for characters with different number are proposed based on the Reed-Solomon algorithm,a partitioning and sliding binarization algorithm based on the sampling threshold is used to keep the anchorpoints,a circle dot filtering with connected region judge is carried out to find the anchor points,and an improvedprojection method is adopted to segment characters. According to the recognition experiments of a variety of samplesfrom different mobile phones,it is found that,with the help of the proposed system,the average correct recognitionrate reaches more than 95% and even 100% with the combination of Reed-Solomon algorithm,and that the proposedsystem is of high efficiency and stability for actual applications with embedded devices.

Key words: Tcode, coding, decoding, recognition, embedded system, binarization, projection
