Stop guessing which OCR engine to use. Super OCR automatically selects the optimal engine combination for your specific image, delivering superior accuracy across multiple languages while handling the complexity behind the scenes.
Traditional OCR tools force you to choose a single engine and stick with it. But what if your document contains Chinese characters mixed with English? Or Japanese text in a complex layout? Super OCR solves this by running multiple engines in parallel and intelligently selecting the best result.
- ✨ Automatic Engine Selection: No more manual configuration or guesswork
- 📈 Higher Accuracy: Achieves up to 98%+ accuracy by leveraging the strengths of multiple engines
- 🌍 Multi-Language Mastery: Seamlessly handles Chinese, English, Japanese, Korean, Thai, French, and more
- ⚡ Smart Performance: Balances speed and accuracy based on your content
- 🧠 Confidence-Based Selection: Uses weighted scoring to pick the most reliable result

# Batch processing
python scripts/main.py --images ./images/*.png --output ./resultsSuper OCR's core innovation is its parallel processing architecture combined with intelligent result selection:
- Parallel Execution: Multiple OCR engines process your image simultaneously
- Confidence Scoring: Each engine's output is evaluated with reliability metrics
- Weighted Selection: Our intelligent agent analyzes results and selects the optimal output
- Language-Aware Optimization: Automatically adapts to the detected language mix
- Chinese documents: 95%+ accuracy (vs 63% with single-engine approaches)
- English documents: Consistent 99-100% accuracy with faster fallback options
- Mixed-language content: Seamless handling without manual intervention
- Complex layouts: Better structure preservation through multi-engine consensus
| Scenario | Single Engine | Super OCR (Multi-Engine) |
|---|---|---|
| Chinese Text | 63-85% | 95%+ |
| English Text | 99-100% | 99-100% |
| Japanese Text | 81% | 97%+ |
| Mixed Languages | Variable | Consistently High |
| Processing Speed | Fast | Optimized Balance |
