QR Code Detection Based on Local Features

2D barcode detection is the initial step for barcode content identification, which is critical for its wide application. A great deal of effort has been made in recent years to develop 2D barcode detection methods. However, less attention has been paid to locate 2D barcode within large background areas. In this paper, a QR (Quick Response) 2D barcode detection method is proposed, which utilizes LBP (Local Binary Pattern) and image contour features. Experiments demonstrate the superior detection accuracy and speed of the method.
