Recognition of 2D Barcode Images Using Edge Detection and Morphological Operation

Bar code recognition has been widely used for several years in many commercial applications. Each symbol which comes into barcode category mainly contains information about the product to which it is attached. 2D barcodes store more information in both vertically and horizontally directions. Common types of 2D barcodes include Aztec, Data Matrix and QR Code. While they all look similar in appearance, each one is encoded in a different formats. The availability of cell phones with digital camera facility provides users a mobile platform for decoding bar code rather than the use of the conventional scanner which is lack of mobility. The motive of this paper is to provide a novel technique for recognition of barcode images captured by mobile phones with the help of image processing techniques. In this proposed work MATLAB platform is used for all processing operations. The performance shows satisfactory results.
