针对QRCode二维码实际情况，设计了基于Canny和Hough变换的二维码旋转校正算法，几何形变校正算法-QR Code for two-dimensional code to the actual situation, is designed based on the rotation correction two-dimensional code Canny algorithm and Hough transform geometric distortion correction algo

二维码图像识别，十分好用，优化的。而且所有的部分都有源码。(Two dimensional code image recognition, very easy to use, optimized. And all of the parts have source code.)

通过ZXing DLL 生成二维码，该DLL 是由谷歌生产，市面上使用率比较高。(Generating two dimensional codes through ZXing DLL)

在线生成带文字和logo二维码 、图片处理、图片合成(Online generation of text and logo two-dimensional code, picture processing, picture synthesis)
