INTRO Last year Election Commision of India made sure that electoral roll cannot be converted to editable format easily by making electoral data into an image format. But image data is not safe now when OCR technology is improving day by day. In this project I have used Tesseract 3(stable) and 4(latest) to fetch data of electoral roll and use strengths of both version to get maximum accuracy.
Tesseract 3, which is stable version till date can be used to whitelist characters, which tesseract 4, which is latest version till date, lacks. Tesseract 4 on other hand have high accuracy on text data.
To fetch data I have used tesseract 3 for numerical and categorical values and tesseract 4 for names.

1)Front Page 2)Electoral voters data

1: Vidhan Sabha 2: Part Number 3: Main Town 4: Polling Station name 5: Male count 6: Female count 7: Total
