Abstract
A method for performing an optimization process on a two-dimension code picture may include the follows. A color filtering process is performed on an obtained two-dimension code picture, and a color-filtered two-dimension code picture is obtained. A median filtering process is performed on the color-filtered two-dimension code picture, and a median-filtered two-dimension code picture is obtained. A binarization process is performed on the median-filtered two-dimension code picture, and a binary image is obtained, such that a two-dimension code in the two-dimension code picture may be effectively identified by utilizing the binary image, and accuracy for identifying the two-dimension code may also be improved.
