Designed and Development of Embedded QR Code Bar Code Recognition System

摘要

Based on J2ME technology, develop a Embedded QR Code bar code recognition system. This system integrated image graying, image binarization, image rotation and other processing methods to realize bar code pre-process, anti-perspective transformation algorithm is adapted to correct distortion pictures, solved mobile taking picture on problems of image lean, distortion illumination on QR code effectively, have higher identification of image under different lighting conditions.
