OMR Sheet Comparison API (Python or PHP)
Budget: $10 – $30 USD
I need a simple script or API that compares two OMR sheet images — one correct answer sheet and one student-submitted sheet.
The API should detect filled bubbles, align sheets, and return a JSON response showing each question’s result (student answer, correct answer, match status, and overall score).
Requirements:
Input: Two image files (correct & student) via POST API.
Output: JSON with per-question comparison and total accuracy.
Should handle minor tilt or noise in images.
Clean, well-commented code with setup instructions.
Preferred Tech: Python (FastAPI/Flask + OpenCV) or PHP.
