See you could go for machine learning using haarcascades (http://docs.opencv.org/doc/user_guide/ug_traincascade.html) or SVM (http://docs.opencv.org/doc/tutorials/ml/introduction_to_svm/introduction_to_svm.html#introduction-to-support-vector-machines)

Another way is you go for detecting features for every particular number and then making the system learn it.Obviously its not that easy as it sounds,you have to go up researching on this. Search up for implemented projects on different platforms like Matlab etc and then implement it on OpenCV.
