Comparison of ocr_utils.py between main and reconcile-improvements branches
==================================================================
Key improvements in reconcile-improvements branch:
1. Enhanced illustration/etching detection:
- Added detection based on filename keywords (e.g., 'magician', 'illustration')
- Implemented image-based detection using edge density analysis
2. Specialized processing for illustrations:
- Gentler scaling to preserve fine details
- Mild contrast enhancement (1.3 vs. higher values for other documents)
- Specialized sharpening for fine lines in etchings
- Higher quality settings (95 vs. 85) to prevent detail loss
3. Performance optimizations:
- More efficient processing paths for different image types
- Better memory management for large images
Test results for magician-or-bottle-cungerer.jpg demonstrate these improvements.
