![]() ![]() QR code stands for Quick Response Code, Which is the trademark for the type of matrix barcode which was invented by the Japanese corporation Denso Wave. Albeit 2D systems use a variety of symbols, they are in general referred to as barcodes as well. ![]() Later they evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions. Primitively barcodes represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional. Index TermsQR code, Universal Product Code (UPC), watermarking, security, data capacity, scratch removal, steganography, encryption, decryption.Ī barcode is an optical machine-readable exemplification of data relating to the object to which it is committed. Thus, this paper is an attempt to highlight some of possible research areas while considering QR codes. Some experiments have also been done for better recognition of the QR code image that includes scratch removal techniques. QR code being so versatile because of its structural flexibility that it leads to so many diverse field for research such as increasing data capacity, security applications such as different kinds of watermarking and steganography as well. #Qr code reader from image OfflineThis also allows offline media such as magazines, newspapers, business cards, public transport vehicles, signs, t-shirts and any other medium that can embrace the print of a QR code to be used as carriers for advertisements for online products. With the technology of mobile phones constantly emerging, especially in the area of mobile internet access, QR codes seem to be an adequate tool to quickly and efficiently converse URLs to users. This paper take account of QR codes basics, its real time application in day to day life and research areas associated. The QR Code system has become admired outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes. QR code is the type of matrix barcode, which was first designed for the automotive industry by Denso Wave in Japan. The particular domain is the information is encrypted or decrypts information it describe particular information in secret code that contain authentication. The recognition of qrcode that was defines by computer or made by the computer its self using some encryption or decryption algorithm.
