## What it is
OMRChecker is a Python application that reads and evaluates OMR (Optical Mark Recognition) sheets scanned via a scanner or phone camera. It uses OpenCV-based computer vision to detect marked bubbles at any angle and color, scoring exams at 200+ sheets per minute.

## Use cases
- grade multiple-choice exam sheets from scanned images
- evaluate OMR answer sheets captured with a phone camera
- score surveys and forms with bubble marks
- process xeroxed or low-resolution OMR sheets
- batch-check exam results quickly and accurately

## When to choose
- you need to grade MCQ exams or surveys from scanned OMR sheets
- you want a free, self-hosted alternative to commercial OMR software
- your sheets vary in scan angle, color, or quality

## When to avoid
- you need handwritten text recognition rather than bubble-mark detection
- you require a polished GUI workflow rather than a CLI/config-driven tool
- your forms are not standard OMR layouts
