Mobile Balance Charging Using Ml Kit and Number Recognition

الملخص

The current progress of technology led to use the electronic devices in every part of our daily life. Mobile charging is one of these daily habits that occur every few days. The use of technology helps persons to compromise many problems.
In this paper, an auto charge application is modified as an automatic packing application for the balance through the mobile camera and without writing any numbers or symbols; it provides solutions to some problems for users who suffer from vision problems or some technical difficulties such as mobile keyboard problems. So the facilities of this application are use the mobile camera to take a picture for the secret number (PIN code) that is on the packing card for mobile networks that are available in Iraq (Zain Iraq, Asiacell and Korek), apply preprocessing techniques for image enhancement, extract the features, recognize the numbers and convert them into a digital form; all this steps applied using image processing techniques (Optical Character Recognition (OCR), Machine Learning Kit (ML Kit)), the final step is add some header and trailer symbols to the recognized numbers and then complete the process of charging.
