supports search in images of scanned paper documents. This process is quite complicated and highly depends on the quality of the scanned image. The lower the quality is, the less "real" text will be extracted from the document.
- Choose high density when scanning - at least 300dpi
- Align the sheets
- Train Tesseract for the specific document
Customizations of the recognition process can be made from the INI file, located in .\Readers\OCR\
