8. Preprocessing of the Photograph... Rotate photograph with buttons : This adjustment must be done by user because it is a bug of Android that it does not offer a proper photograph meta data.

9. Preprocessing of the Photograph... Border Detection of the Coupon : Borders of the photograph is detected and unrelated parts are discarded.

10. Preprocessing of the Photograph... Perspective Correction : Images acquired through cameras suffer from projective distortion, uneven lighting and lens distortion. We use methods to remove these effects/distortions for intelligent processing of images

11. Line Detection Detect the two lines that every coupon has and seperate logo part from number block and number block from the below barcode part. : Logo image goes to logo matching process and number block goes to OCR.

12. Logo Recognition Logo image coming from line detection is processed and its keypoints’ descriptors are calculated. : These descriptors are then compared with the 4 different games’ logos’ descriptors in the database and best match is returned. OCR Number block’s image coming from line detection is directed to OCR black-box to get numbers. : We used Google’s Tesseract OCR by training it with our supported coupon types’ fonts for 40 times!

13. Showing Results Getting The Internet Data : Application will connect to Milli Piyango website and download the latest draw results in every launch. Comparing The Numbers : Played numbers and the draw results will be compared.
