An algorithm correcting Flex distortion of Aztec code

As 2D bar code Aztec Code has a lot of outstanding excellences such as high capacity, high density, strong error-correcting ability and security, it is widely used in online tickets sold. According to the practicability, this paper has designed a system processes Aztec code stretching Distortion. In this paper, the algorithm of 2D bar code is introduced in detail. It can be also used in other similar domain.
