I need a suggestion about my project,i have to create an program that can read the crossed choice paper and grading the student according to the point they got in the question.
- So how should i approach this ?
when i'm using ocr all the text are gone.
Here is the example, I can manipulate this all i want as long as it's a Cross choice like the q1-5 and have more than 50 question
By the way, Sorry for bad english.

I wouldn't go the OCR route, but instead try to find on which letter there is more black than usual. The built in OCR from Matlab is terrible and it can be quite complicated to get an external method to work. Counting pixels on the other hand is easy to implement.
