## Best Practices
### Image Quality Guidelines
For optimal OCR results, follow these recommendations:
```mermaid
quadrantChart
title "Image Quality Impact on OCR Accuracy"
x-axis "Low Quality" --> "High Quality"
y-axis "Poor Results" --> "Excellent Results"
"Blurry Photo": [0.2, 0.2]
"Dark Scan": [0.3, 0.3]
"Good Photo": [0.6, 0.7]
"Professional Scan": [0.9, 0.95]
```
### Do's ✅
- **Use good lighting**: Ensure even, bright illumination
- **Keep it flat**: Place documents on a flat surface
- **High resolution**: Aim for at least 300 DPI
- **Straight angle**: Capture from directly above
- **Clear focus**: Make sure text is sharp and readable
- **Contrast**: Dark text on light background works best
### Don'ts ❌
- **Avoid shadows**: Don't cast shadows on the document
- **No skewing**: Keep the camera parallel to the page
- **Don't crop too tight**: Leave some margin around edges
- **Avoid glare**: Watch out for reflections on glossy paper
- **No low light**: Dim conditions reduce accuracy

## Tips for Better Results
### Handwritten Notes
Handwriting recognition can be challenging. 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:

## 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
