Research on the Graphic Correction Technology Based on Morphological Dilation and Form Function QR Codes

As a kind of widely used form of two-dimension codes, the QR codes have been widely applied in various aspects of our life, but in the process of the use of the QR codes, the QR code images captured often suffer from deformity because the QR code label is attached onto the object irregular surface (for example, a curve surface) or the camera and the QR code label are different in position, therefore, the QR code image recognition correction method based on the shape function has been put forward and verified, with the experimental results showing that the improved algorithm can restore the graphic effect.
