HC2D barcode reader using embedded camera in Android phone

Abstract

The HC2D barcode is a highest capacity of 2D barcode while it occupies a small area. The size of the HC2D barcode is suitable for displaying on print media such as paper and poster. But, for reading the HC2D barcode, the bit representation of the barcode is obtained by scanning the image of the barcode with scanner machine only. This paper shows the implementations of image reorganization of HC2D barcodes in mobile phones with android operating system. The mobile phone system used here consists of a camera, mobile application and display device, and the source image is captured by the embedded camera device. The introduced algorithm is based on the code area found by two vertical line, one horizontal line and dash line detection of HC2D barcode. This algorithm is robust for the real-time recognition of the HC2D barcodes and an average recognition rate is 91.33%.
