1. A method for performing an optimization process on a two-dimension code picture, comprising: performing a color filtering process on an obtained two-dimension code picture, obtaining a color-filtered two-dimension code picture; performing a median filtering process on the color-filtered two-dimension code picture, obtaining a median-filtered two-dimension code picture; performing a binarization process on the median-filtered two-dimension code picture, obtaining a binary image, and utilizing the binary image to effectively identify a two-dimension code in the two-dimension code picture.
