Abstract
This paper describes the basic information of QR Code. Especially for the blurred QR Code image, we put forward an improved NAS-RIF algorithm which makes bimodal characteristic of the barcode image into it as a constraint. NAS-RIF algorithm itself has a good convergence speed. It will effectively improve the recovery effect of barcode image after combining with bimodal limit. The experiment shows that the improved algorithm not only enhances PSNR but improves the visual effect of the restored barcode image.
