Abstract: QR codes are the most widely used in two-dimensional barcodes nowadays. Image pre-processing is an important process to achieve QR code image recognition in complex conditions and ...

Before you start looking for algorithms, you need to clearly define your problem and its scope. What is the goal of your image processing or computer vision project? What are the inputs and outputs?
