2D Barcode Image Decoding

2D Barcode Image Decoding

Barcode technology is one of the most important parts of Automatic Identification and Data Capture (AIDC). Quick Response code (QR code) is one of the most popular types of two-dimensional barcodes. How to decode various QR code images efficiently and accurately is a challenge. In this paper, we revise the traditional decoding procedure by proposing a serial of carefully designed preprocessing ...

Detecting and Decoding Algorithm for 2D Barcode

2D Barcode can be classified mainly in two types which are stacked 2Dbarcode and matrix 2D barcode. This paper discusses structure of types of 2D barcode in brief. This paper will propose flowchart of detecting 2D barcode and also decoding the 2D barcode.

2D Barcode for DNA Encoding

The paper presents a solution for endcoding/decoding DNA information in 2D barcodes. First part focuses on the existing techniques and symbologies in 2D barcodes field. The 2D barcode PDF417 is presented as starting point. The adaptations and optimizations on PDF417 and on DataMatrix lead to the solution – DNA2DBC – DeoxyriboNucleic Acid Two Dimensional Barcode. The second part shows the DNA2DB...

Camera Phone Based Barcode Decoding System

We propose a 1D barcode acquisition and decoding system based on the use of J2ME enabled mobile phones. The approach relies on image processing techniques to correct the distortions introduces by the acquisition device, segments the useful information, decodes it and subsequently sends it to a web server for further processing.
