问题
I need to develop an application which detects QR codes with Visual Studio 2010 and OpenCV. I am very new in this topic. Can someone explain in simple words the steps of the decode algorithm and the procedure to detect the patterns in a QR code? I have read the steps in the ISO/IEC 18004:2000 document but I don't understand well. Thanks in advance
