The main function is to identify the code number. The algorithm used is based on artificial neural network model, through training and save the full sample values (and the number of features), training to recognize the picture after the number (256-bit color), I believe that neural network model for the study was helpful, while the code is also involved in image processing part of the contents, such as binary, gradient sharpening algorithms to noise.
