Recognition of Lottery Digits Using OCR Technology

Unfortunately, there is very little opportunity for disabled people to get a job, especially for the visually impaired. Most of them survive by selling lottery tickets but it is difficult for the visually impaired to know the digits on a lottery ticket or the results. This paper presents an algorithm to recognize lottery digits and development of an application to read and check the lottery digits. This is achieved by using the Tesseract OCR engine in a mobile application. The procedure includes the following, adaptive thresh holding, connected component analysis, location of text lines and digits, recognition of digits pass 1 and pass 2. The operation of the application will result in 6 digits scanned from the lottery ticket. Then each generated digit will be played through a prerecorded voice. The results of Alpha and Beta testing with 100 sample tickets showed efficacy of recognition and prize checking at 98.05% and 100% respectively. In conclusion, the results showed that the application has a good accuracy level and can be use in a real world scenario successfully.
