tesseract /path/to/image.png stdout

# Specify language (Chinese + English)
tesseract /path/to/image.png stdout -l chi_sim+eng

### Quick Examples

```bash

## Notes

1. OCR accuracy depends on image quality; use clear images for best results
2. Complex layouts (tables, multi-column) may require post-processing
3. Chinese recognition requires the tesseract-ocr-chi-sim language pack
4. Language packs must be installed separately on your system
