| Abstract: | According to the characteristics of camera phones and the issue of the binarization in the QR code recognition,a binarization method based on surface fitting technology is proposed,using two-dimensional second-order polynomial fitting way to the QR code background image of the surface fitting,and image segmentation.Experiments show that the method can better solve the problem of the QR code image binarization under the uneven illumination conditions. |
