Improve results by: 1. **Write clearly**: Use legible, consistent handwriting 2. **Use lined paper**: Helps maintain straight lines 3. **Dark ink**: Blue or black ink works best 4. **Adequate spacing**: Leave space between words and lines ### Printed Documents For printed materials: 1. **Clean scans**: Remove dust and debris before scanning 2. **Standard fonts**: Common fonts recognize better 3. **Good contrast**: Ensure text stands out from background 4. **Complete pages**: Avoid cutting off text at edges ### Complex Layouts When dealing with multi-column or complex layouts: ```mermaid flowchart LR A[Original Document] --> B{Layout Type} B --> C[Single Column] B --> D[Multi Column] B --> E[With Images] C --> F[Direct OCR] D --> G[Process Each Column] E --> H[Text Extraction Only] F --> I[✅ Best Results] G --> J[⚠️ May Need Manual Fix] H --> K[✅ Text Extracted] style I fill:#c8e6c9 style J fill:#fff9c4 style K fill:#c8e6c9 ``` --- ## Understanding the Processing ### What Happens During OCR? When you click "Generate", Noterich performs several steps: 1. **Image Preprocessing**: Optimizes the image for recognition - Auto-rotation correction - Contrast enhancement - Noise reduction 2. **Text Detection**: Identifies text regions in the image 3. **Character Recognition**: Converts image pixels to text characters 4. **Post-processing**: Formats and structures the output text 5. **Insertion**: Places the result directly into your editor ### Processing Time Typical processing times vary based on: | Factor | Impact | |--------|--------| | Image size | Larger = Slower | | Text amount | More text = More time | | Image quality | Poor quality = Additional processing | | Server load | Peak times may be slower | **Average time**: 2-5 seconds for standard documents --- ## FAQ ### General Questions **Q: Is there a limit to how many images I can process?** A: Noterich provides generous limits for OCR processing.
