Hi Raj, ¿is there a possibility you could send me your language "sun" to test the Seven Segment OCR out?
I am unsure at the moment which is the best way to attack this problem, either with Tesseract or OpenCV and the fact that your solution is giving 100% accuracy on your tests gives me hope for Tesseract.
